But the Protestant work ethic is good! There are hard-working people who are still poor, but there are very few situations where you, or anyone else, will be better off being lazy instead of working. (Hard manual labor that harms you permanently in some way, like old coal miners, is probably the biggest exception.)

In the counterfactual, where these hard-working poor people are lazy instead, they aren't suddenly rich or even the same as they are now. They're almost certainly worse off.

I was raised with a strong work ethic. Do I believe that working hard is the only reason I am where I am now? No, of course not. But if I didn't work hard my life would be worse in every way imaginable! Regardless of how lucky or unlucky your life is, having a solid work ethic will always always always make you happier. Work is not inherently 'bad' in some way, and neither is having to work to live and to learn and to have a good life.
