When Red Line Entry says "its all about money" that is, in my opinion, not quite correct - but the financial aspect most certainly is a major factor.
Nobody has alluded to the fact that last year was the 65th anniversary of the end of WW2 when millions of Service Personnel returned home after years away.
The "happy reunions" with loved ones resulted in a massive baby boom in 1946/7 and the millions of male babies who have survived to celebrate their 65th Birthday will retire this year and next in receipt of the State Old Age Pension. At the same time, of course, National Insurance contributions will suffer a major decline and there will be an increasing burden on Local Government Social Services and the NHS.
The Coalition may have secured a narrow majority but they also inherited a "poisoned chalice".
