Actually it is "Promote the general welfare" no where in the Constitution does it advance the providing of "free services" to a segment of the society. You should look into what "free medical care" has done to the countries now providing it and how medical care declines in a government run medical society.
I know all about that.
That's why I specified people who CAN'T help themselves. There's a huge difference between them and people out for freebies.
