I don't think that's true. Coming from Germany I feel that in the average US citizen living as an employee has less rights and freedoms than the average German citizen. In principle you can live a very free lifestyle in the US but you either have to have lots of money or check out from the lifestyle most people live.
That's true. If you want freedoms and rights in America, you're either not a part of the 'normal' American way of working and likely not making much money, or you're wealthy. Workplaces are authoritarian and remove a lot of rights when you walk in the door or sign into your computer, even doing surveillance on work devices that are further than simply asset tracking & data protection.
