The trend towards globalization has been ever increasing.
Economic borders have been shrinking.
This is primarily due to trade zones, i.e. NAFTA, Euro, Trans Pacific-Partnership and many regional ones.
These type of trade agreements are often criticized. The criticism centers around the terms of the agreement.
Countries feel like they are not getting a fair deal, citizens believe they will be harmed and private enterprise holding a vested interest.
Many large scale trade agreements are often done in secret with little civilian oversight, transparency and heavily sculpted by private enterprise.
