$24.8 billion last year which is more than they got from oil. 10% of that would be $2.4 billion so in 5 years the wall is paid for. I like it.
Hasn't Donald Trump also said that he would have all the illegal Mexican immigrants removed from the country within two years? So in considerably less than five years you will have no remittances left to tax. Or best case scenario only a fraction of the $24.8 billion worth.
