Skilled parents are more likely to have skilled children. Even ignoring any possible hereditary intelligence correlation that might exist, having good job prospects will naturally heighten the chance of their children doing well.

There are also more than enough skilled people waiting to come here. With a backlog of skilled works the west has the opportunity to be selective (refugees are another subject). I personally support the idea that they should be more open to skilled workers. Although Canada already does a pretty good job compared to the US. Apparently the UK is looking into copying Canada's policies following Brexit.

But even here in Canada skilled immigrants often get associated with unskilled or illegal immigrants, or just generally misunderstood in terms of the value they bring, which (unfairly) puts pressure on reducing numbers.
