Good points. People work in jobs like slaves, because their employers know that their lives depend upon their jobs. Now, let's assume that you were a millionaire and were just doing your job for fun. In that case, your employer would basically have no power over you, since he/she knows that you have enough money to survive anyway. Now that is indeed freedom! So, you are right, having money = freedom!
But I am of the opinion that with increase in AI and tech, one day we would have a post scarcity economy. We already saw it to some extent with the advent of open source and free software. Once that happens, people could at least be given the basic necessities of life without any charge.
No one is going to give you anything though. Sure people could provide the basic necessities right now for everyone and aren't willing to do it. Don't assume people will give and just learn how to use the system (capitalism).
