Obama and Chabolas.

Back in the 80s, outside Madrid, there were tens of thousands of 'homes' put up in shanty towns. These were called chabolas and were filled with poor people from rural areas who wanted to live in the big city. El Ayuntamiento, or council, found them the equivalent of council flats to live in and then bulldozed the chabolas.

So. What would you expect to happen next? - Well, of course. In the poor rural villages the news spread like wildfire that 'if you spent a while in chabolas', the Council would then house you. The consequence was even more chabolas. It took decades to sort out the self-inflicted problem.
It would be rather nice if President Obama were able to understand simple concepts. Legitimise illegal immigrants and you encourage tens of millions more! In the UK I have heard Obama-logic from far too many of the liberal left to mention!
