For most of our history immigrants were free to come here if they could get here and they had to sink or swim meaning there was no welfare system for them. This was OK as it was a win-win. But after the welfare state was created, there was an incentive to come here for the welfare not just for the opportunity. This changed everything. Now there are many more things to consider; water, waste, agriculture, pollution, etc. A more conservative approach is needed. To help people in the rest of the world, we need to help them where they live. We need to encourage the rest of the world to adopt our system of government and economic system. It is obviously what the people want.
