While President Trump is no stupid man, his belief that building a
border wall would win the drug war displays a real lack of understanding
of the laws of supply and demand. If
you put the squeeze on supply, prices will go up thereby giving others
additional incentive to enter the market despite risks. The only way
that Donald Trump or anyone else can possibly win the war on drugs is by
turning America into a total police state, with cameras in every room
in every building in the country, including homes, as well as body
cameras and mandatory daily drug testing for everyone in the country.
And even that still might not do the trick. Don’t forget: They can’t
even keep drugs out of prisons.
