$130 billion per year in foreign remittances by over 35 million illegal aliens in the US. Not 11M like Obama would con you into believing, No wonder Western Union was fined last week $586 million for aiding and abetting money laundering, lottery fraud and human trafficking of illegal aliens (details on this blogfeed)
Payroll tax evasion, suppression of industry prevailing wages and displacement of US workers are other consequences of remittances.
Let put some teeth in passing the 7% tax on the Remittance Status Verification Act. 7% of $130B will pay for the WALL in 1 year.
