If we tighten up our own population that doesn't mean we're going to produce more children. There is a correlation between education and how many children a woman bares. Remember in Quebec when they were willing to pay 500$ to any woman who had more than...was it two children? Well x amount of children anyway in an attempt to preserve the French culture. It didn't work and many were insulted.
The only way you're not an immigrant is if you're Native anyway. An interesting sidenote: Economists widely believe that diversity is the key to a successful society. With the advance of minorities and women in the workplace our economy has flourished. We basically need these immigrants.
A lot of people seem to be responding with the answer that we're not setting a good example etc. etc. These are real people, and sending them off just because we want to save face is pathetic. How will it look, how will it look? Who gives a damn how it looks, the question is if it's right or not.
