That’s true, some people are not cut out for it. But I can tell you that there are a lot of kids who COULD do it if they pushed themselves. They just don’t want to because its too hard and they’d rather do other things (like party). And then they complain later on about their employment prospects.
That being said, over time, these things tend to even out. Engineers may start out making more, but they often plateau quickly. On the other hand, the English major may find out he is a natural for sales and earn megabucks.
“who COULD do it if they pushed themselves”
Met plenty of those. Sorry, I take conversations like these to heart and know I shouldn’t. Sore subject for me right now.
