"On average, smarter people make more over their lifetime than less smart people bro, that is a fact!"
1. Can’t predict the future.
2. How does the finer division by non college jobs look like? Electrician is one of the top- how does it compare to a doctor accounting the medical debt?
3. Average college debt is 30k. Hardly crippling.
1) You cannot predict the future, but expecting that current situation will hold indefinitely isn't a safer bet either. I think the best you can do is observe the trends.
2) Of course, I would recommend anyone to take the more compensated route, trade or college but it is probably easier for someone of average academic aptitude to become a good electrician than a good surgeon or a good programmer. That is the point.
3) What are the interests? I heard quite a lot of horror stories regarding the interest rates on college debt. Interest rate for non-trivial principals is the most important parameter of any debt.
Your "period" makes me think about more questions, not less.
1) Will that still hold in 2070? Kids who are now 18 are likely to be working at least until then. How do the developments over time look like? Won't the increasing shortage of tradespeople drive up their compensation?
2) How does a finer division by majors look like? I would be surprised if every major out there made more money than, say, an electrician.
3) Lifetime is a very long timespan. College grads are deeply in their debt in their 20s and 30s, so they can afford starting a family less. They will be better off when they are 50, but in the meantime they possibly sacrificed a an unborn kid or two to their tuition debt. This is a nasty tradeoff.
