We let sex perverts in.
We currently have a set of stupid immigration laws left over from our Thatcher copying Tory government of a decade back. Either you have a lot of money, or a degree. Except all the jobs we're short on are plumbers, electricians, taxi drivers, etc. Shit you don't usually get degrees in. We need manual labour, that's why big business here wants open borders with China, but thenthe Tories go ape, and try a coup, and the Labour party can barely keep their controlling coalition under control and really fuck NZ politics they are worse than little kids.
Who the fuck cares!
