Long term investments - Well placed homes, precious metals, long-term market commodities, etc.What meets your criteria?
There are loads of investments, most of them don't actually pan out well, that is why investing is a hard way to make a living (otherwise why work?).
I wouldn't say 'most' when referring to long-term investment. Many things people invest in short-term, yes.
Hopefully people are not borrowing money to buy ammo.
This is the USA, I'd bet a whole bunch of people have racked up the credit card with firearms and ammunition over the past few months. Sad.
