Normal people don’t just borrow our of necessity, they borrow because it’s smart money management, particularly while rates are low. I finally “broke even” 3 years ago on my house. But instead of paying it off, I paid the minimum and invested the rest and made a 90% return over 3 years. I’m definitely not rich, I was poor until a few years ago, but I definitely took advantage of that loan and now it will pay for my retirement
