Lex, it sounds like you assume too much about me from an article. First of all, I am not a trust fund kid, and I have been working during my uni years as well.
I founded my first company at the age of 18, and been working on that while finishing 2 BsCs and an MSC.
Granted, I moved to Europe, where education (If you have good results) and health care is free.
The article is about working for other people may not be for everyone.
I know it is not for me.
Besides, being an entrepreneur is a far cry from a side-hustle. As a human scale business owner I had to build all the processes on my own in the beginning. I was the CEO and the janitor the same time.
I wish you and your kids all the luck, hope they don’t end up living under a bridge as you so kindly wished me.
