Real, actual people exist who turn down raises because they're convinced it'd cause them to lose money, because they don't understand how marginal tax rates work. I don't mean low-income earners who may in fact lose out or not gain from a raise due to benefits cliffs, I mean people earning low-six-figures who think if their pay goes any higher "my tax rate will go up and I'll lose money" and are weirdly resistant to being convinced otherwise.
