Balls. There are plenty of young people interested in and investing the time in aviation.
Off the top of my head, I can name ten students aged 14-20 who were at my UK flying school in the last year. And very enthusiastic and hard working they were too!
When you consider the formidable challenges, not just financial but also economic and political their generation faces, their perseverance in funding licenses and training becomes even more impressive. Not one of them would turn down a spare seat going. And not one of them said "nah, I'll just play on my XPlayStationBox".
