The basic premise of economics (and many other social sciences) is that "People Respond to Incentives". Here is another example (via Jack):
[W]hile Manitoba offers legal aid to refugees, the provincial government confirmed in an email that Saskatchewan is one of four provinces that does not. ...
"If someone is making a refugee claim in Saskatchewan they have to spend their own money from their own private funds to hire a lawyer and they simply do not have any money," [Winnipeg attorney] Khan said.
The lack of aid is leading many refugees to chose Manitoba over Saskatchewan, he said.
