How did we get to two levels of citizenship in this country ?
Same way we got "minority" preferences in college, in-state tuition rates for illegals, and gay-"marriages." Sedentary citizens, scheming politicians, and tyrannical judges who don't obey the law.
Read up on your history, we didn't even get to become citzens until 1924! Then we were finally allowed to vote in the 1940's. We've found a loophole in the laws and now that we are making big money, you guys can't stand it. All it takes is for fools to stop going to the casinos and handing us their money!
It's all because of that pesky Constitution thingie. Get rid of that, and then everything will be "fair".
It's in the Constitution, and in the whole bucket of increments that made the US.
