Britain came out of WW2 deeply fcuk'd. We'd lost the Empire, owed the US a crapton in loans, and then were economically smothered under a nationalisation programme that wiped out UK manufacturing competitiveness. At least we got the NHS (no small thing) and a passable social security system out of it. The economy we have today is the one Maggie re-engineered in the 1980s. Even the Blair government had the good sense to not dare touch it.
