Earlier quoted context omitted.
Don’t you think that we got things like women’s suffrage, paid vacations, democracy, public healthcare, free public education, modern medicine, engineering, etc precisely because idealists can have an impact?
"Women’s suffrage, paid vacations, democracy, public healthcare, free public education" are just results of societies getting richer. Luxuries that become affordable for regular people. There has been some idealism in tech, and I don't mean just modern tech, even long before the first flight, but you can't say that it's wasn't also being beaten into place.
And if being rich isn’t enough but it also requires the will of some people to push these ideas through and realize them, then wouldn’t you call those people... idealists?
If not, I’d love to hear what definition of “idealist” people are using in this thread, because it just sounds like a no true Scotsman argument.
