Because the harrier guy has been selected at all stages for his SKILLS rather than how much money is in daddy's wallet.
Without getting into the whole CTC vs self-improver debate, which has and continues to be done ad nauseum here, one question - why is it always assumed that it's 'daddy' who pays?
There are plenty of guys and girls who do CTC/Oxford/other fATPL sausage-factory and put up all the money with all the associated risk themselves.
By all means argue against the route into the industry - I very much do not like what it has become (it has changed substantially since I started at CTC way back in the day) and I absolutely understand the arguments being put forward against it here. Sometimes I look out of the window on a 4hr+ sector with the AP on and wish I'd given myself the chance to experience more 'proper' flying before getting into an Airbus. I wouldn't let my kids follow the same career path that I have so far for a multitude of reasons.
But from first-hand experience, this notion that all integrated fATPLs have been given a £120k present from rich relatives is, in the vast majority of cases, inaccurate. There are a few, but they are the exception rather than the rule.
