Its not good advice for everybody, but it is good advice for a lot of people. What if you want to be a doctor? What if you want to work in R & D? Not everyone enjoys working in a shop or a farm. Also, how old is your friend group? If they are mid twenties you are ignoring the greater scope for advancement in a lot of white collar careers.
> my 25 years old friend with her own shop knows more about real life, business and economy than ivy league MBAs.
Within the narrow limits relevant to her business. How much does she know about macro-economics or financial economics, or scaling up a business? I also suspect you are comparing her to people who went straight on from bachelors to MBA (which is a bad path - study business after having some experience IMO) and lack experience. How will she compare in 10 years time when those people also have real world experience?
If you’re talking about a place to mature, around others who are at a similar phase of life, also yes.
It is where most people meet their cofounders, for example, even if they don’t found anything until much later.
Plenty of blue collar workers make more than white collar ones, and have a huge debt free head start in life.
A plumber or electrician will make significantly more than the average bank employee or translator or nurse or teacher.
And they will also have an easier time starting a business as many trade workers are self employed and make much more than hired ones.
Financially, intellectually, socially, it’s a good idea - college is a formative period of life in American culture. That is more and more true the better the college gets. At the upper tier (Ivy League, etc.) you don’t really have to pay anything if your family isn’t already wealthy, and the connections and degree you’ll make more than pay for themselves.
Many people are surprised to learn how affordable elite colleges are if you genuinely need financial aid. I had no idea -- was pleasantly surprised when my alma mater took over 80% off of my tuition.
Where I live it's basically free and I still sometimes regret not going into the trades. But I suspect this feeling might mostly be a "grass is greener" thing.
Just some anecdata, but every single one of my university professors was quite bad, but they think that since they are the professor, that means they are smart and the expert.
