If you had the option to finance a car with an adjustable rate loan, with zero down and no payments for five years, I hope you wouldn't do it. You would be upside down immediately. By the time the first payment came due, you'd already be looking for a new car, and actually owe way more than when you bought it. Borrowing to finance current consumption is a recipe for financial ruin. Most financially responsible people recognize this and live accordingly.
So why do we let previous generations do this, but pass the bill for their expenses to us? We're still paying for the waste and wars pursued by long dead political leaders. That is tragic.
Incredibly, we still refuse to admit we can't keep borrowing forever, which means we're trying to push the burden on to our children. That is shameful.
