I've worked very hard to get to where I am, so working hard isn't difficult for me. I chose to work here because it provides the best life for me, not because anyone forced me to. Would you rather take this choice away from me?
What you think is "best for you" changes for a lot of people over time. Meanwhile, using my iphone analogy again, you are merely raising the cost of a phone for those who "just want a phone". ie, you are raising the expectations for employers who will expect more people to work for 40+ hours, while getting paid for 40.
If you are from a country with a long waiting time for a US green card, you should really look at a moving to another developed country, or marrying a local.
