In short, a parliamentary road to socialism is impossible, a dangerous delusion. But, that's not just the case in relation to socialism. The ambitions of the petty-bourgeoisie, as represented by Brexit, Trump, et al, also, threaten the interests of the ruling-class, which is why its state, what the Trumpists call “the deep state”, has acted to limit that damage by whatever means it could. We can only assume, in current conditions, that were Starmer (written before my prediction of the Blair-Right counter-coup was fulfilled) replaced by Farage, who would be forced, having presented his betrayal narrative, to even more extreme and irrational measures, that the capitalist state would be led, itself, to resort to even more drastic measures to constrain him, and the damage he might do.
“Saint-Simon showed the same superiority over his contemporaries, when in 1814, immediately after the entry of the allies into Paris, and again in 1815, during the Hundred Days’ War, he proclaimed the alliance of France with England, and then of both these countries with Germany, as the only guarantee for the prosperous development and peace of Europe. To preach an alliance with the victors of Waterloo to the French in 1815 undoubtedly required somewhat more courage than to declare a war of tittle-tattle on German professors.” (p 333)
The last sentence refers to Duhring's conflict with other professors at Berlin University, as referenced earlier. Unfortunately, the rapidly rising power of Germany, by the end of the 19th century, meeting the established power of France and Britain, at the same time as the rising power of the US and Japan, meant that, short of the workers of Europe, themselves, seizing power, and bringing about such a unity, its inevitable manifestation would come in the form of imperialist war and annexation.
Both France and Germany recognised the need to create a single European economy and state, but France, as the established power, saw it as its prerogative to dominate it, whilst Germany, as the rapidly rising power, sought to challenge that prerogative. Britain, as existing world hegemon, had no desire for a large European state on its borders, which would rapidly overhaul it. So, Britain acted to frustrate the ambitions of both France and Germany, setting one against the other. Millions died in the ensuing conflicts.
“If in Saint-Simon we find a masterly breadth of view, by virtue of which almost all the ideas of later socialists that are not strictly economic are found in him in embryo, we find in Fourier a criticism of the existing conditions of society, which, while genuinely French and witty, is none the less penetrating.” (p 333)
The bourgeoisie, in its revolution, had seen itself as representing the whole of society's interest. It mobilised the other oppressed classes on that basis, promising them Liberte, Egalite, Fraternite. But, the antagonistic class interests mean that was never possible, and, as soon as that revolution was completed, that reality became apparent. Rather than Liberte, the glaring disparity between what was promised and what was delivered, meant that the bourgeoisie, as ruling class, and its state, had to impose its own restrictions on the freedom of the great mass of society, who saw no sign of the Egalite and Fraterenite, they had been promised. One of the most egregious examples of that, of course, was the denial of liberty to millions of colonial slaves. As Oliver Cromwell Cox has described, it was to try to reconcile this contradiction that the bourgeoisie put forward the idea that not all humans are “equally human”, so that some humans do not have the same right to freedom. It created racism. As Cox describes, before then, no such explanation, nor ideology was required, because previous modes of production never claimed that such equality of rights existed. They all took it as normal that society was divided into ranks based on status, into separate estates, each with their own specific rights and duties.
