That's a very shallow outlook, especially in business.
What if you go to a USA wholesaler, buy the goods, get home, sell them and then find out 90% of them are faulty? What you going to do if the wholesaler has spent all your money? Beat him up? That will get your money back

Worse still what if he has gone out of business?
There are risks with any purchase, not just losing your money overseas.
If you deal with a genuine overseas company you will pay your money and receive your order.
