Eva is correct. Immigration is neither necessary nor is it “good for the economy”:
Every non-Western immigrant that enters The Netherlands puts an average strain of €600.000 on the Dutch national treasury. Yet many people still believe the diabolical lie that immigration is necessary to solve the aging population issue. The opposite is true.
Immigration cannot solve the birth rate problem because the loss of a net-productive native cannot be replaced by one, two, or ten net-negative immigrant. In fact, the more immigrants, the worse the problem will inevitably be.
Karl Denninger calculates that less than 15 percent of all US immigrants contribute anything at all. The percentage that are net-positive could be under five percent, which obviously cannot even begin to compensate for the negative effects of their fellow immigrants, let alone the native shortfall.
