It’s called money laundering. The IRS should make sure that the money sent was earned legally and taxed. Those businesses doing the transfer should keep records and report to the IRS. Proper (legal) identification must be given by the sender.
There’s no tax at all.
I see it every day. Contractor hires subs to do the work. They have one legal Hispanic who owns the business. His 20 cousins are illegals and get paid cash. They send cash out of the country.
We pay for their healthcare, their kids public schools, and get NOTHING in return.
Trump is right!
