Absolutely not. The French revolution overall had enormously positive effects on Europe in terms of equality. A quick look into that period across Western Europe will give you numerous cases where suddenly the powerful became uncharacteristically eager to let go off significant parts of their power. In fact this event may well have had the biggest such effect of any event in history.

A recent event last year in the US also immediately resulted in actions undertaken whereas peaceful protests did not. Mostly protective actions, but it showed a very clear impact, the contrast was stark.

Based on what? Sure quips like that are catchy, but what "oligarchs" were there in the Soviet Union circa 1920-1989? The "nomenklatura", while well-off, were absolutely nowhere near the wealth of today's American oligarchs or modern (capitalist) Russian ones. Moreover, unlike oligarchs, they do not form a class: wealth does not transfer reliably one generation to the next, and individuals would phase in and out of high status according to their position in their career.

A very striking way to illustrate this is to look at the career histories of high government officials even very late into the Soviet Union. The last Minister of Coal, Mikhail Shchadov, was born in a village, worked in a mine, went to mining school for engineering, became head of his mine, and thereafter worked his way up the ranks until he was head of the whole apparatus. This story, not that of inherited wealth or monopolistic oligarchs, dominates the histories of Soviet ministers even very late in the decline of the Union.

Where is the "other set" of oligarchs of which you speak? There is none, which means there is hope for workers who might wish to enact fundamental economic change.
