You have a contradiction in your logic. Poor people working "regular, shitty, low-paying high-demand jobs" do not have savings. The numbers may vary somewhat by country but here [1] they are for America. 85% have less than $10k. 50% have less than $1k. 34% have $0. And there's probably going to be a pretty good correlation with savings and income. The 15th percentile in household income is about $120,000. Interestingly enough indicating even relatively well off Americans are awful at saving!
Interesting! Those data are indeed specific to the US and I expected the numbers would vary by nation, but not radically so. I enjoy learning more about economics and the fact there is a nation where even the poor have substantial savings is quite bemusing to me! Do you have any sources available?
