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.
Not opinion, fact. The Constitution states any authorities not EXPLICITLY granted to it in The Constitution are restricted. Given your past demonstrations of your legal prowess I am not about to get into a debate with you about constitutional law. If you want these programs so bad make it happen privately and voluntarily through charity programs, nothing is stopping you. You have no right to take the resources of others by force and redistribute them let alone put the government in a position of creating dependence on it for survival. Under The Constitution the people are the masters and the government it's servant. Under your system the government is the master and the people are it's servants. That is the exact opposite of what The Constitution says.
