Late Stage Capitalism

This idea that the only condition necessary for (successful) revolution is for conditions to get bad enough, ignores the fact that conditions have been extremely shitty for large numbers of people for long stretches of time. There have been plenty of people suffering under colonialism or slavery, and even without that, people in the past were much poorer in general.

Mismanagement and abuse by the king and aristocracy was by no means a new thing. All across Europe, throughout the middle ages, kings got into long, bloody, expensive conflicts that left them unable to pay their debts. The solution, generally speaking, was to blame the resulting problems on Jews and use them as a scapegoat to cancel the government's debts and expel them from the country, seizing whatever assets they had in the process. Or just don't pay your soldiers what they were promised, which happened often (in spite of the risks). In the meantime, of course, you remind everyone that they will get to enjoy eternal paradise, but only if they accept their lot peacefully.

The French Revolution started because the king got involved in a very expensive conflict, the American Revolution, which created a debt crisis. That part was nothing new. What was new was that the bourgeoisie class had developed substantially and possessed much greater wealth and power than they ever had before. Furthermore, literacy allowed people to question the narratives that had previously kept them loyal and passive. They weren't going to accept, "We can't pay you what we promised, sorry, the Jews did it" and they had sufficient power to back it up.

Crucially, it also allowed for communication and unity between the politicians of the National Assembly and rural peasants. Without that, rural peasants might see them as persuing their own aims in a way unconnected from their own problems (and contrary to their traditional beliefs and values). This would in turn discredit the National Assembly and make it harder to see them as representing anyone or negotiating with any power behind them.

"When all you have is a hammer, everything looks like a nail." If you lack imagination to think of a way things could be different (and how to get there), then you will only double down on the frameworks and solutions the system provides you with. Prayer, racial scapegoating, etc, no matter how illogical they may seem from the outside, without literacy, the only solutions you're likely to find are the ones based on things you already believe.
