Your beloved white mobocrats are always busy organizing on you, lobbying for higher pay or more benefits, and doing it all while they're on your dime.
You mean the pregnant Mexican women who cross the border expressly to give birth to an "American citizen"? Or Asians who immigrate to Rhode Island and Minnesota (among other states - those are two states where family members have first-hand experience) and immediately join welfare rolls?
What's amazing still is the high level of immigration, considering the near-Fascist condition in which American business exists - the increasing amount of control that Federal, state, and local governments exercise over how business is conducted and how individuals live their private lives.
