Acadian,
I take it you have a job which offers benefits? Are you aware that more than 50% of jobs in my area do not come with benefits? What if everyone would "take care of themselves" like you suggest, could you also suggest a way for them to do such? I guess they could quit their job without benefits and go search for a job which does have benefits, but then, we are mostly talking jobs which require higher education. What if they don't have higher education? Oh, and we would also need to close all restaurants and all small retail stores, because such places never offer benefits, so if all their workers quit to "take care of themselves" then they wouldn't have anyone to work for them.
It all comes down to this.. Person X grew up in a poor family and they couldn't afford to send person X to college. Now person X takes a restaurant job which doesn't pay great to start with, and it also doesn't pay benefits. X really wants to take care of himself, so he works a second job in order to get ahead in life. Lo and behold, person X gets sick and needs to go to the hospital. His savings are used to pay off hospital bills. Oh yes, he tried hard to get some cheap health care, but he had to show proof of income, and honest as he tries to be in life, he shows them all his pay stubs. Damnit wouldn't you know it, he actually makes a few dollars a month too much to be eligible for the health care plan. But now he is sick and all his savings are gone. So much for X trying to take care of himself. FYI, nearly ALL of my co-workers (including myself) are in this situation, making just a few dollars a month too much to be eligible for a health care plqan, yet not making enough to be able to afford real health insurance, and not making enough to afford getting seriously ill.
