Statistically you are more likely to make more money with a college education. However, the college versus trade school should be decided on an individual basis.
I agree with the author in that every student shouldn't be pushed to college just because college graduates tend to make more money than blue collar workers. American culture definitely places a college education as preferential to trade school. I think it would be beneficial for the country to realize that going to trade school can be a good, lucrative career path for some people.
If everyone could do it, it'd be best to all go to college and become lawyers, doctors, and bankers yet not everyone can. Many Americans probably get sent down the college path only to end up as baristas making $30k/yr after 4 years of $40k+ tuition when they could have done a year of trade school and be on the path to making $100k+ a year as an electrician.
There is a high value to being an educated person that's hard to quantify. At the end of the day I'd rather be a barista who writes art exhibition critique on the weekend than an electrician who watches Dancing with the Stars re-runs every night.
