Few options.

Find an employer who is willing to hire you and go through H1B visa lottery, which is the normal work visa.

Enroll in a US university, ideally a STEM degree, and use the OPT visa extension to get a foothold in the US.

Marry an American?

Probably plenty more options, but I'm not an expert in US immigration.

Join a company based in the US (like many tech companies), and do a really good job. They will then start trying to get you to move to the US, under an L1/L2 (if you can handle management, L2 tends to be better as your partner/spouse can work).

Immediately apply for a green card.

Preferably be born in a small European country, so the green card comes in your lifetime.

So looks like it's not too easy, which means salaries will not get better in Europe anytime soon.

Meh, it's not impossible. You probably need to move to Ireland or the UK though, as that's where most of the larger tech companies have most of their roles.

Invest 500k+ in the US to get the investor visa.
