Immigration Costs and Global Warming Costs
Meanwhile, in the real world (according to a conservative who's trying to beat the Left at the self-congratulation game), Non-Western immigrants consume 59% of Denmark’s tax surplus. That sounds like they're saying “OMG, the Third-World hordes are eating 59% of our taxes!” but it's actually something marginal. Some people believe the horrifying apparent implication.
The really interesting point is that the actual amount is $2 per Dane per day. (For Americans, it's around $1 per American per day. Those figures are of the same order of magnitude as the estimates of the Social Cost of Carbon.
I won't more than mention that the costs of educating the second generation are compared to the taxes paid by the first generation in these calculations instead of to the estimated taxes that will be paid by the second generation. (The second generation usually earns more and pays more taxes.)
