The Conservatives did not pull the UK back from the financial crisis. Gordon Brown did. The crisis was caused by the sub-prime mortgage crash in the US, as everybody knows.
All the Project Fear about the UK going bankrupt was nonsense. A country with its own sovereign currency cannot go bankrupt.
The coalition government decided (against the advice of many) to bring down the deficit by cutting the state rather than raising taxes. This was ideological rather than sound economic management. The Conservatives have never believed in raising taxes to pay for anything. As a result, the poorest have paid for bringing down the deficit, but the public debt has tripled, which is a bit like remortgaging.
On paper, there might be almost full employment in the UK (which makes me wonder why Brexiteers squeal about those foreigners taking our jobs), but the quality of jobs are poor (low pay, zero hours contacts, etc). Not only that, but the unemployed on work programmes don't count in the unemployment statistics, nor do 16-18 year olds since the raising of the school leaving age. The UK's productivity lags behind that of other major economies.
None of this matters if you're one of the "I'm alright Jacks", who is financially comfortable and is unaffected.
It will be interesting to see what the Conservative manifesto omits. Look out for pensions, raising of the state pension age again, no commitment to raising public sector pay, no promises not to cut working age benefits, no promises for health, social care or education, no commitment to not raising NICs, etc. I expect there will be some meaningless promises about mental health and grammar schools, etc.
Facts show that the Conservatives have historically not been responsible with the economy, unlike the claims of tabloid hacks.
