"The average remittance sent to Mexico in 2015 was $292.00"
A small, 1% or 2% "fee" on remittances should be enough to pay for a very nice wall and would still be cheaper (and safer) than sending bundles of cash via Fedex.
im not just looking to build a wall, I think we need to stop the cash drain as well. that money needs to stay in the US and be spent in the US to provide jobs in the US
