Please tell, where in the Constitution does it say that the state (AKA taxpayer) is responsible for providing for the well being of the poor or indigent?
I suppose we can eliminate your stated violation of the Constitution by adhering to my point concerning the Constitution.
It doesn't say it in the Constitution because the Constitution was written for a free people imbued with the Christian virtue of charity and during a time when it was entirely possible for anyone with shit, grit and a little mother wit to make it in the world.
The plain simple fact is that people trapped in cities with no real chance at gainful employment present a problem to our society. Unless we do something meaningful to help these people, we are going to have both a permanent under class and a permanent criminal class. People robbed of their dignity and with no hope present a grave danger to our society.. not to mention that it is a national shame that we have fallen to such depths.
If you want to get technical, forcing someone to give his or her bodily fluids for government inspection is a clear violation of the 4th Amendment.
It's a clear violation of the common law notion of privacy.
It is an affront to human dignity.
I don't want my tax dollars paying for it.
It is up to thinking conservatives to build a government that allows and encourages people to take care of themselves. Somehow, I don't think forcing them to piss into a cup helps that goal along.
