The illiegals not working is a whole other ballgame. Most who work are on a payroll system. For every nanny or day labor paid under the table, there’s 50 thousand of them working for large companies and paying witholding (no, e verify does not always work)
Do you have a source for that assertion? And are you implying that illegal aliens are net contributors to the nation, i.e., benefits received versus costs incurred?

E-verify is a voluntary program except in a few states like AZ. There are about 400,000 employers enrolled in the program with about 20 million vetted thru the program. It does not cover the majority of the workforce. It is not mandatory to use it.
