Yeah, the gap between the wealthiest and everyone else literally does not matter at all, when it comes to 'motivation for revolution'.
The overall level/amount/condition of poverty is what matters. And let's be real, things are not nearly as bad in the US today as they were in France before the French Revolution. Not even close.
Fact is, if you magically bumped everyone up so that no one was making less than $75k a year, the wealth gap would be essentially identical to what it is now, because the gap between zero and 75k is nothing compared to the gap between 75k and hundreds of billions. But no one would be suffering in poverty, so would anyone care about the wealth gap, then? I seriously doubt it.
McDonald's double cheeseburger hasn't been a dollar for over 15 years (started in 2002, and in 2008, the McDouble replaced it, which had one fewer slice of cheese). And the McDouble itself stopped being a dollar in 2013, over a decade ago. Bit more than "a few years ago"--I think Covid screwed up everyone's perception of time more than usual, lol.
That said, I get lunch at work several times a week at Wendy's and always pay less than $5, not too bad all things considered imo.
