Dunno, I like to think there's an honest way to it. To give back. I think education might be the driving factor for creating change but sometimes people don't want to change for one reason or another, or it's too difficult to, because change is difficult. To build a company. One that isn't about the money accruing although that's the nature of businesses to thrive. So to come back to your question, I guess you're right.

Only if you're lucky.

Probably

There are a few examples that look less like exploitation than others. Like e.g. the lottery?

I mean you can be rich very fast with crypto [and probably stock] market but it sometimes sounds as if you exploit other people's stupidity to become rich.

Yes. But it's harder.

Nope, nobody becomes rich alone and you won't get rich compensating others equal value for their labor - building wealth depends on exploitation

Yes, you just need to be born in a rich family. :—)

Yes, although I do like watching scambater youtubers waste scammers times

Winning the lottery?
