Add in that what today appears a safe and secure path is not guaranteed to stay that way. Economic conditions go through cycles, the realities and requirements of careeres evolve, as has been discussed on this thread. Outsourcing, obsolesence, etc may become an issue, even if it doesn’t look likely today. I have no quarrel with the choices anyone makes, or why-different strokes for different folks-but I wonder how many are banking on security that may not last.
When I was in high school, the “best” careers, i.e. high paying, secure, and prestigious, were doctor* and lawyer. I don’t recall engineering being talked about much (but that may be because I’m female and it wouldn’t have been suggested to us 
). There’s much more emphasis on STEM these days, at least compared to when and where I grew up.
Today the “it” career is Computer Science. Will that be true in another decade? The “it” career 20 years into the future probably hasn’t been invented yet. And so on.
*I recall a lot of the top kids planning to be doctors. At the first or second high school reunion I remember being rather shocked at how many lawyers there were.
