Admittedly I may have thin skin on the topic, but your words didn't just refer to the actual obtaining of a degree but rather people who could have gone to college. Perhaps I'm projecting as I could have gone but didn't and have regrets simply in that it was a challenge I missed out on, or that I get tired of bring treated like a dummy because of what I do for a living. However, it felt like from what I quoted above you were discussing intelligence more than the mere college education. You can have one without the other.
I realize that most cleaners you know didn't go to college, but that doesn't mean they couldn't have or weren't smart enough. There are loads of morons in college, lol. A degree doesn't mean what it used to.
Anyway, glad you found something that works for you. Sounds like you have a good business. There are lots of good businesses out there, many of which require no college. There is so much opportunity out there. In the end it isn't about how much money you make or if you have more degrees than a thermometer, it's about how happy you are in life.
I am one of those that makes decent money. The two of us working together make pretty good money. We are in the trenches every day. As far as money goes, at a point it's not how much you make, but rather what you do with it.
