I wouldn't say this is entirely true, because we still have youth engaging in learning skill, but it has really reduced drastically compared to the 90s. I think the access to internet in our country really contributed to it.  The internet is a very good thing, because it has a lot of benefits,  one which is the online jobs your mentioned .
The major problem why most youth are not interested in learning skill is that they want to get rich so quick,  that they venture into G and other unthinkable things just to make money, but I am very sure that we still have youths in this country that are really engaging in learning skills and trade.
