Perhaps you would quote the portion of the Constitution that forbids government charity.
Sorry, you have got it backwards. The 9th Amendment says:
The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
So as far as the federal government is concerned, they don't have such power unless it is enumerated. So now perhaps you would quote the part of the Constitution that does this...
