>And how did they get those capital, for instance the CEO of Meta?

This is the right question.

I'll quote myself here:

1. How come people are able to accumulate so much capital?

2. How come people are able to use the capital to influence life of other people in all ways possible to their liking?

Yes code and capital are both "tools". But you can't just right some code and install cameras at every corner. You need some political influence to do so. And capital buys you this influence.

And to get this capital you should have laws that allow you to do so (tax rates, evasion etc).

Same goes for political influence.
