Looked it up:
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.
It’s not “despite” the gap, because the gap itself does not cause poverty. If the poorest person in the US made $75k/year (in other words, poverty completely eradicated), the size of the gap would still be pretty much exactly the same (after all, the difference between zero and 75k is nothing compared to the difference between 75k and hundreds of billions, which is the current net worth of those with the most wealth).
After all, 50 years ago, the gap was significantly smaller, but the overall incidence of poverty was much higher.
Someone’s always going to have the most. And new wealth is constantly being created. And net worth is a valuation, a price tag, not an amount of cash (which is the primary reason it can go up as fast as it can–cash money simply can’t do that). Given these facts, expect this gap to always exist (and almost certainly continue to widen), even after poverty is eradicated.
