I think you always want your children to go through less hassle than yourself?
I personally believe that guiding children through struggles we experienced is not a good idea of parenting.
Disclaimer: I didn't finish college as well, for same reasons as you.
Edit: I've realized my comment might've sounded like a critique of your parenting methods or anyone else's. That wasn't my intention, just that I know that it's hard to realize those things sometimes, especially if you're not a parent. I've always seen making life easier for your children as a bad thing, now I see this as the most important thing to do in life. It gets bad when you could move it further, helping people around making their life easier, but you don't - essentially making sure money "stays in family".. Again only my 2c.
