I don't know what you should do, but just keep the following in mind:
- For high income America might be a better place. But it's also more expensive. So is money really what you want, or do you want a good happy life?
- Depending on your home country, immigration to the US can be hard. Getting a work visa can also be hard.
- University is expensive in the US, unless you find a way to get funded. But if you are US educated it becomes easier to get a job in US.
- I barely remember what I learnt at uni ;)
- Did you try getting into FAANG or similar? If I were in your situation, that's probably what I'd do.
- If it's wealth that you're after, then it's a totally different game. Understand how money works, and carefully play that game.
