For the SWP, the political extension of this strategy, which amounts to Economism/Menshevism, did not apply, because, unlike Militant and the Bennite Left/CP, it had no orientation to the Labour Party. The ironic consequence was that, its petty-bourgeois, Third Campist, moral politics meant that, come elections, it was led into a bankrupt “lesser-evilism”. It not only called on voters to just passively "vote Labour", to avoid the Tories winning, no matter how bad Labour's politics had been, and were likely to be, but they, also, were left proclaiming, that “for the next six weeks of the election, we will be the best supporters of Labour.” A bit like the Brexit/Lexit position they adopted later, they excluded themselves from the political struggle within, but then had to simply go along with the rules and decisions that came out of that struggle anyway!
The SWP, instead, pursued its Luxemburgist strategy, by which this mounting wave of industrial struggle – which for the reasons already described, was, by this time, on the wane and undermined by the growing relative surplus of labour – would, somehow, mystically transform itself into a spontaneous, political, revolutionary, class consciousness of the workers, who would, then, storm the barricades and seize state power.
The reality of the Militant position, was, in fact, not too different. Although, they propagandised week after week for the reformist idea that a Left Labour Government could, “nationalise the 200 top monopolies”, its leaders, who had been around in the Trotskyist movement for several decades, must have known that such an idea was preposterous, and had been shown on numerous occasions, when tried, to simply lead to the ruling-class and its state, destroying the government, and, if necessary doing so by means of extreme violence. The example of the coup against Allende's government in Chile, in 1973, was fresh in everyone's minds, were they to have forgotten, all the previous examples. Sections of the ruling-class had even discussed a coup against Wilson's social-democratic government, for goodness sake, so what would they do to a Left Labour government?!
The leaders of Militant must have known that, at the very least, even a Workers Government, would, as Trotsky described, baulk at breaking with the bourgeoisie, requiring a mobilised revolutionary proletariat, already organised in workers' councils/soviets, to control the streets and workplaces, to already be a workers' state in waiting – a condition of dual power. The trouble is that, it was no good the leaders of Militant knowing that, if even their rank and file members did not, let alone if the working-class they sought to lead was not schooled in that reality. Anyone who argued day after day with ordinary members of Militant could see that those members did not understand that reality, and they would try to give chapter and verse from Marx, Lenin and Trotsky on why a “parliamentary road to socialism”, was possible, and so sounding more and more like, simply more militant versions of the CP, and Bennites.
As Trotsky noted in relation to the German Revolution and the Chinese Revolution, in the 1920's, when it comes to revolutionary strategy and tactics, timing is crucial. Calling for General Strikes or for the creation of soviets requires that the workers are on an upward path of struggle, and that, revolutionaries have been preparing the advanced sections of the class for the raising of such demands, so that the workers know exactly what the implications of them are. If you continually call for a General Strike, in conditions where the working-class is not strong enough or confident enough, it will be mere revolutionary phrase-mongering, and demoralising. At best, the workers will not respond, at worst, they will respond in a weak and confused manner and the state will suppress them. All-out General Strikes are political strikes, they are revolutionary acts, which directly pose the question of which class rules in society. Trotsky described the mistakes made in that regard in Germany, in the 1920's.
But, as he set out in relation to the Chinese Revolution, it is pointless to refuse to call for the creation of soviets, as the Stalinists did, until such time as the condition of dual power exists. The soviets implies a revolutionary situation, and the workers need to be armed to defend those soviets, and ensuring that those arms are available and go to the revolutionary workers, not their opponents requires time, planning and organisation. In other words, instead of leading, the Stalinists ended up “tailing” the working-class, and even the peasantry. The Stalinists, who had adopted the Menshevist “stageist” theory, in which the proletarian revolution could only come after the bourgeois-democratic revolution had been completed, were forced to adopt this stance, because they had tied themselves to the bourgeois-nationalists, of the KMT, and this Popular Front required that the interests of the workers were subordinated to those of the bourgeoisie and petty-bourgeoisie. Stalin repeatedly denounced Trotsky and his supporters – including some Chinese Communists, who did not even know they were supporting the line of Trotsky – for creating conditions in which the KMT and the Chinese bourgeoisie would split with them.
Stalin was still promoting that line just days before Chiang Kai Shek launched his coup in Shanghai, and slaughtered thousands of Chinese Worker Communists. The Communist Party and its fellow travellers have pursued the same Popular Frontist strategy ever since, with just the brief interlude of the period of sectarian madness of The Third Period. But, the strategy of the SWP has followed the same Popular Frontism, in search of building the widest possible coalition of forces on one issue after another, as their answer to everything sank into the idea of building the next ever bigger march or jamboree. The same souffle politics was adopted by the Stalinists and their periphery backing Corbyn, via Momentum, and it suffered the same fate as all the other such ventures, deflating on contact with the slightest external pressure.
The conditions, by the early 1980's, had already turned in favour of capital, as it had responded to the crisis of overproduction of capital relative to labour by carrying through the new technological revolution, based around the microchip. In industry after industry, technology replaced labour, particularly skilled labour, such as in the printing industry. Those that had thought that the old Economistic strategy of industrial struggle could simply continue, and would become even more radicalising for workers, as it sharpened, were guilty of the same kind of catastrophism of Sismondi, and of the Stalinists of the 1920's. Rising economic stagnation, and unemployment acted not to turn workers into class conscious revolutionaries, but to undermine even their ability to maintain wages, to keep their organisations together. Increasingly, it turned workers not against capital, but against each other, as they competed for work.
