I mean, they are so rich, they can start to mine Bitcoin, even if they lose some money they shouldn't care, they are ok with all those money they already have.

Yes , you are!!!
Because rather than asking why the "rich" guys aren't fixing

More miners would have no real impact on the confirmation speed. The time between blocks will decrease for a while but with the difficulty adjustment it will go back to 10 minutes a block.
One miner or 1 million it doesn't matter, it's not like sending 100 more trucks to carry gold from a mine.
Mining at a loss is not the solution to solve the transaction problem. We have to think of better solution.
