The Manhattan Institute's Diana Furchtgott-Roth, who used to write for the New York Sun when I worked there, has a nifty column linking the current Republican push to end birthright citizenship to the passage of ObamaCare:
It's no coincidence that the debate over birthright citizenship has sprung up in the wake of the expansion of the welfare society enacted by Congress and the Obama administration - accompanied by prospective tax hikes. European countries cannot welcome immigrants because the welfare benefits they confer upon their citizens are simply too expensive to offer to newcomers....
As America slouches towards the European economic model, the European immigration model appears newly attractive. The European economic and immigration models are complementary - we need to reject both.
