> I'm going to guess that either you already own your home and your car outright
Partially correct.
Yes, I own my car. While I was in school my family bought the cheapest used vehicle there was so that I could go to classes. After I graduated, I continued using that car until I had made more than enough money to buy a new one. I have friends who took on massive amounts of debt in order to have luxurious vehicles right after graduation. I will never do something like that.
Yes, my family owns their homes. Both my parents worked jobs while renting an apartment until they had enough to buy the home I grew up in and in which they live in to this day. It took a lot of effort.
Yes, my education was fully paid for in advance. My parents prepared and planned for it since the day I was born. My father showed me his careful accounting on his ledger, entries dating back decades.
> Or you're wealthy to the point of being able to pay cash or make major purchases without having to save for a while.
Wealthy enough to pay cash? I guess. Without any planning and saving? No.
> Credit allows me to buy the house NOW and start building equity NOW.
What did you really buy? Fail to make your payments and see the true owners of your house take it away from you. None of it is real until the payments are done.
> Student loans were a good idea, but ended up with disastrous side effects
Of course. That about sums up the entire history of credit and debt. A great idea that destroys everything.
> But to argue for the abolishment of credit because some people suck at it is just throwing the baby out with the bathwater.
> It would absolutely destroy the middle class and kneecap upward mobility of the lower class.
On the contrary. Credit and lending are literally responsible for global economic collapse. It destroys the lives of so many it's not even funny.
