You've banged on about the first part before, but why is it relevant to a debate on school standards being affected by kids? The parents don't go to school. (And I'd question the quality of some European degrees, as someone who knows people who've studied in most countries on the continent, on a year abroad from the UK - some courses are a joke.)
Educational standards of children are strongly correlated with their parents for starters. Moreover, it various studies it has been found the immigrant children have better educational standards on average.
Your quip at European degrees is ridiculous, do you think that some
EX-polytechnic,bottom of the table, UK college is some how superior to every continental school? That is a ridiculous unfounded statement.
With the second part - London schools perform better, but that doesn't mean migrants/children of migrants aren't negatively affecting the development of 'native' kids, unless you can evidence that claim?
If you believe immigrants are negatives forcing British born children then the onus is on you to find evidence.
Immigrants/children of immigrants perform better as they're more hard working and so forth - why can't that explain the better performance of the schools? (So essentially the argument would be that the 'native' kids perform the same, or even worse, but the affect on the average of the hardworking 'immigrant' kids outweighs that and leads to an overall figure that looks very positive).
The elevated performance of immigrant children is what explains the increased average performance, there is no evidence for any strong effect on British born children. What were you expecting?
Overall. But not all of them. The position could arguably be further improved (a greater overall net contribution) if the net drains within that group were stopped from coming here.
Possibly, but possibly not. The problem is how do you know who will be a net drain or contributor a priori, and how do you devise a system that would be guaranteed to I prove the average, and at what cost will that have? E.g., has soon as you have any kind of visa requirement then you break the dynamic market driven free movement of people which help increase British GDP. One can simply look at non-EU vs EU migrants, the Non-EU under go much more control but their average contribution is lower, so trying to control the immigration has provenly Ben worse between the 2 separate population pools. EU immigrants already contribute far in excess of British citizens on average so it isn't clear how much better on average you can make it? Do you have any proof that the net contribution could in erase from 34% to say 45%, and what the costs of that process would be and any other pros and cons?
The other thing is even if a migrant is a marginal negative contributor there are a number of associated cost advantages that are not fully taken into account, such as labor training costs. This would also ignore the possibility that there are jobs that there is a worker shortage for in the UK but the job still pays minimum wage, which makes it hard to be a strong positive contributor but Britain gains from the immigrant regardless.
Beyond that why worry so much about a small group of net contributors when a majority of the UK population have a negative contribution? Time, resources and money should be spent on improving the british workers average continuation , reducing benefits fraud, increasing efficiency and costs of raising a baby to a productive adult, attracting foreign business etc.
As an analogy you have a few k sitting in a savings account that can earns 2% interest. With a lot of effort by having must,pile different accounts and switching funds around monthly you could get an average of 2.7% interest, worse still some of the account have 90 day access clauses etc.. Sure that is better average return but not by much and it has some cost. Meanwhile your house that is worth 500K has a giant while in the roof, rain I pours in and is rotting the wood, soon the bedroom ceiling is about to collapse. Now why are you so concerned about rias g the interest rate of a small savings account by a small amount. With all that fuss and bother when there are much more important things to look at that have a much bigger financial impact.
