I believe the original plan post-TSR2 was to get some F-111s but the F-111s overrun so much and the cost went up so much that the plan was abandoned.
sidslotm is right though, the will to work has gone out of the UK, I don't know why, some would probably blame it on the benefits system but this problem has been around longer than that. Perhaps it's an over-reliance on technology, I don't know...but we're certainly not the nation of grafters we once were.
Of course, I speak generally rather than specifically, naturally there are exceptions to the rule.
