The government's role is to protect its citizen's constitutional rights. That is it. Not to feed, house, educate, medically treat, employ, etc.
That's nothing more than an "every man for himself" attitude. Nothing more than your opinion. The constitution sets out things like "to form a more perfect union", "to insure domestic tranquility", "to promote the general welfare", "to secure the blessings of liberty". The argument can easily be made that to ensure the government achieves those goals, they needs to do some of the things you outlined to some degree. This is another case where you state something as a fact when it's nothing more than an opinion.
