Nobody can make you feel inferior without your consent. - Eleanor Roosevelt.
I've no problems with any of the rules that come along because it was my choice to work in the US on H1B.
A correction: "I have 6 years of time-frame to get that Green Card." -- You have more than 6 years. In the given validity of H1B visa, you just have to get your I-140 filed, after which you can file for yearly increment of your H1B visa.
If you think you are free, Just quit your job for few weeks (over 60 days), and see what happens. Illegal. Stay without a job over 6 months, and you can't get in the US for 10 years. Try to work another job, (that is not related to your profession), and it is considered illegal employment. It can be Automatic deportation. Even if you want to part-time DJ (for fun), can be considered automatic deportation.
Also, a lot of very early stage startups don't want to deal (or don't have time and money) with such immigration hassles.
Sorry, this is not complete freedom. I am treated relatively well by my company, and make good money, but I'd also like to have the option to just quit, and work something out of my own, and see where it goes. I can't right now, and neither can you, unless you want to go back to your country, and say this country good bye for good.
Not saying that this is how it is (I haven't studied the matter), but your argument is worthless.
