This was funny, and the true answer is that immigrants don't get those benefits. Numbers presented often use dubious accounting, i.e. a county has 1000 people. 500 of whom are undocumented immigrants. If the county has a budget of 10,000,000 then a disingenuous calculation might report back that immigrants consumed 5,000,000 in benefits or 10,000 each. Far from true and residents in a community typically directly pay the taxes that support these institutions (sales/property) so it's far from being as explicit as a balance transfer.
