1) we are the right sized population
2) we are a welfare state
3) We have enough resources to keep them going for years.

5) we would get the BBC instead of Fox.
6) we would have TVR dealers ( auto content)

2) we would have $2/litre gas
3) The euro pols are even worse than the Liberals when it comes to getting on the gravy train
