They are when our economy and our social welfare systems are already collapsing and when the unemployment rate for Americans with comparable education levels to the illegals in question is 30.8% among all U.S. born citizens, 26.4% among U.S. born Hispanics, and 53.9% among U.S. born Blacks.
The principal of subsidiarity requires that we take care of our own first, before moving beyond our direct duties. No country can afford to provide welfare to the world. As another FReeper posted elsewhere, charity does not require self-destruction as part of the process.
People signed onto a suicide pact when they never demanded the funding assumptions built into SS, Medicaid, and Medicaid, change to reflect their desire to murder the children who were supposed to be paying for those things. Those are the welfare programs that out of control. The welfare programs that keep the slaves on the welfare plantations are destined to eliminate themselves since welfare plantations are part of an old, old, democrat eugenics plan. With roughly sixty percent of assisted abortions being abortions of black infants you can see the end of welfare plantations coming no matter how many flukes with twelve kids someone can dig up.
But I see your perspective, the ongoing mass murder of infants isn't important even if it is the primary cause of our problems with immigrants and with the economy. The real problem is how expensive it is for you to help pay the taxes all those aborted infants should be paying.
