The Great Mexican Wall

The multi-billion-dollar wall construction is actually dividing the world in line of richness and eventually it will backfire on the US itself. Instead of constructing the walls, they can guard the borders with the help of man, machinery and technology. Deter, isolate or destroy Mexico financially will be an easy task for the US in the current circumstances.
Trump can persecute Mexico in the name of trade deficit. But the implications are many and not only the Mexicans, but the US citizens too will be forced to pay high prices for all imported goods in to their country.
High import duty and subsidized local supply will also corrupt the country’s tax structure. In 2015 it was estimated that there was a trade volume of $531 billion between Mexico and the US and as of today Mexico is the third largest trading partner of the US after China and Canada.
The wall's construction and proposed unfair tariffs on Mexican goods and services are actually a disproportionate punishment to their known offences committed on the US soil. Moreover these reckless actions might push Mexico to hard days ahead and Trump is indirectly helping China to become stronger in terms of trade matters too. The rich are supposed to feed the poor.
But they are building walls in places of bridges. Financially crippling a country for nothing is not going well for a civilized world. As Martin Luther King Jr. rightly pointed out, injustice anywhere is a threat to justice everywhere.
