What is so hard about sealing the border?
If its a good idea to have a million new immigrants each year, then fine, make the argument. Lets have that discussion, nationally, publicly. What we must not do is simply accept that number because that happens to be the number that walk across the border.
Immigration policy must serve the interests of citizens. It should never be simply a tool for adjusting wages, or a means for undermining labor law, or a way to adjust voter demographics. It should serve the interests of citizens, and whatever number we arrive at, whether 300,000 a year, or ten times that number, the leadership should be able to explain how that number was arrived at, and why that number is the right one, and not some other.
Far from installing a guest-worker program, I would favor a moratorium on new immigrants for a few years, restricting it to family members of citizens, and a very few others.
The notion that immigrants take jobs that Americans don't want is a distortion of truth; they take jobs that Americans don't want at the price offered, and the conditions offered. Close off illegal immigration and wages for these jobs will exceed legal minimums without any need for a minimum wage law, as employers suddenly have to compete for workers.

Do our politicians and our soldiers have the guts to shoot all Mexican males approaching the border?
That makes too much sense. Who are you? Are you from around these parts? :)
