It's very hard to compare the current situation with pre-revolution France. The 3 estate system that defined France before the revolution is a very special separation of the social structure that does not exist in the world today.

To summarize this system, The first estate was the nobility which had possession of the land, and was politically in charge of the country. The second estate was the Church, they also had some land, and could taxe the third estate in some way. They couldn't do whatever they wanted on the taxe side, and the history about the evolution of taxes used by the Church is a highly complex subject that I won't jump into because I don't know enough about it.

For the most part these 2 estates couldn't be taxed by the King.

Then the third estate was composed of everybody else. Ranging from the rich bourgeoisie to the poorest of agricultural worker. They were the only one that were taxed.

The Revolution started in France more because the Bourgeoisie was started to get richer than the nobility and demanded to be represented in a politcal way.

So it's really hard to make any meaningful comparaison, on one side you would have the nobility owning most of the land, the rest owned by the church. But on the other side you have the bourgeoisie starting to get really rich by way of commerce and proto-manufactory.

Moreover, most of the population worked in the fields, meaning the comparaison is really hard to make, how do value the wealth of someone who own a house and is more or less paid in food (overly simplified here).

So yeah, the situation in pre-revolution France is so different to today it's really hard to compare, the inequality was economic/social/political. Today with it being "mostly" economical it's hard to correlate anything meaningful. Too much has changed in the socio-economical structure to use the ancien régime as a way to comparate.
