While that may be Nice, I don't think it's very realistic. Someone leaving flight school right now, joining Ryanair - rubbish as it is, will see you in a much better position, having earned more money in 5 years, than the old school self improved route.
I don't think this says anything about the attitudes of new pilots. Just that those are the options available. 2 years as an instructor earning a pittance, 2 years as a TP FO maybe 30k pa and then hopefully a jet job. Vs add a little to your already enormous debt, earn better money and have the option to move on with a solid TR in your pocket.
It's naive to bash 'the stupid kids of today' for picking what clearly represents a better return on investment.
