They use it to get the earned income tax credit and bennies.
“Many” of them are using “multiple” SS#. They use one to get free housing, free food, free medical care and more....they use another one to gain employment.
The employment one... they do pay some “initial” taxes. But in the end they come out ripping us on that one too. Because they have been allowed to claim many dependent children.
At the end of the year they pocket thousands of our tax-dollars into their pockets by way of earned income credit and other loopholes.
They have been fleecing the honest, hard working American for far too long! If the IRS wanted to stop it ....they could, IMO.
