I grew up during the tail years of communism and everybody was dirt poor. The interesting thing is, nobody was financially stressed, starvation and homelessness was not a thing. I ended up developing an abundance mentality and terrible money management skills.
Looking even further back, my parents experienced the height of policy stupidity and barely survived the great famine which killed millions. It scarred them for life, but also pushed them to make more money and live frugally even after achieving financial security.
