Do you think it's a tad unwise to buy (relatively speaking) unneccesary stuff on credit?

What would you be willing to buy on credit?

In my opinion, i think it’s a waste of money for the average person to buy anything other than a house and a car on credit. I’m talking of things here, so for the sake of the question, ignore things like student loans and medical necessities etc.

Of course, everyone is free to waste their money as they deem fit…but not to the point where they get into financial trouble and are not able to afford paying for the things they’ve acquired.

Plus, can one really have peace of mind knowing that all this stuff is bought on credit – it would feel like a heavy weight hanging over me.
