Like i said i got your sentiment, but there will always be people at any top so to say on that basis that revolutions don't change anything, i think, is not as correct as we all could be.
If i'm right in my feeling that that is basically what you are saying. You have a better recall for history than i have, still as for the French Revolution
The new regime
The National Constituent Assembly completed the abolition of feudalism, suppressed the old “orders,” established civil equality among men (at least in metropolitan France, since slavery was retained in the colonies), and made more than half the adult male population eligible to vote, although only a small minority met the requirement for becoming a deputy. The decision to nationalize the lands of the Roman Catholic Church in France to pay off the public debt led to a widespread redistribution of property. The bourgeoisie and the peasant landowners were undoubtedly the chief beneficiaries, but some farm workers also were able to buy land. The land transfer was made through the sale of assignats, bonds that were issued by the National Constituent Assembly and guaranteed by the value of the church lands. The bonds were to be retired once the transfer had been completed, but within a year, assignats in varying denominations were being printed as a form of Revolutionary currency, with predictable inflationary effects. Having deprived the church of its resources, the assembly then resolved to reorganize the church, enacting the Civil Constitution of the Clergy, which was rejected by Pope Pius VI and by many of the French clergy. This produced a schism that aggravated the violence of the accompanying controversies.
