Why not?

Everything they have in the U.S. is the product of illegal activity.
All of it is basically stolen, it should have gone to a legal U.S. citizen.
The job they held was at the expense of a citizen, the welfare they collected was paid for by U.S. citizens.
Illegals get advantages that actual citizens do not, they get to skirt taxes, while collecting on social welfare programs they do not pay for.
Money remitted to other countries is money taken out of the U.S. economy.

Why should we not retrieve some of these stolen assets once their status has been confirmed?

Do you also object to seizing assets from drug dealers after they have been convicted?

The short answer is it is not politically feasible. It will be an all out battle to get even a little of what I listed. To demand what you are asking will never fly. To clarify my previous answer though I do agree that stolen property should be seized and returned to the owner. I don't think deportees usually get to take much with them anyway.

As for the drug question; it depends on what property and who actually owns it. But that's apples and oranges.
