Purely from a financial point of view, it was a weak governement that allowed a massive influx of migrants without checking that they could contribute to the economy.
Immigration has increased steadily, since the 1950s, and successive governments since the 70s have promised to tackle the problem, with little success. There are several reasons why.
We're part of the EU and thus cannot stop anyone from a member state from coming here and working, if they so wish. The other issue is the Commonwealth countries, and that's a far more complex matter. Almost every member of the former colonies was granted British Nationality in the 1948 act, which allowed them to enter the UK. In 1962, the Immigrants Act reversed the automatic right to settle here. But your facts about immigration are wrong, Fester. Research published by University College London in July 2009 showed that EU migrants made a "substantial net contribution to the UK fiscal system",
paying 37 per cent more in taxes than they received in welfare payments. However, "EEA national(s) who are economically inactive, including A8 and A2 nationals will not generally be entitled to income-related benefits".Researchers found that, on average, A8 migrants were younger and better educated than the native population, and that if they had the same demographic characteristics of natives, would be 13 per cent less likely to claim benefits and 28 per cent less likely to live in social housing.
Asylum seekers and refugees are the third group, and here again it's interesting to see the trends. The numbers applying as refugees and asylum seekers have fallen dramatically since 2002.
Weak leadership led to the relaxation of borders, and the increase in crme.
Your point about crime, however, is interesting: according to the British Crime survey and Police figures overall crime in the UK fell steadily between 1994 and 2010, and has started rising again only in the past 12 months, showing a 2% rise which, incidentally, excludes the riots. Knife crime is seeing the greatest rise but, overall, between 1998 and 2010 crime fell by 16%.
