I don’t think the whole thing is a fraud. There are always some people that take advantage of the situation.
We'll never know how many because the government isn't going to check at all for under $150,000. EVen above that amount, does anyone really think they're going to check? They gave out these "gifts" to 4.9 million companies, so far. More with the new bill they;re working on right now. There's no way they have the IRS investigators to check. And if they check, the business owners will say they're out of business. What's the IRS going to do.
For those still in business who had business still working, they can show they paid their workers as required by the rules. Other money the received from the government paid rent and other costs. However, since the government paid these costs means that income from sales had no costs. So there were higher profits which goes to the bottom line and in the owner's pocket. The owner got a bonus thanks to you and me. How's that fair, equitable, or make sense from and economic standpoint?
