A U-turn in globalism

Currently we can see a U-turn in globalism. The majority of the US population is against the TTP,which had been described by some American politicians as the "gold standard" for trade agreements, even including Hillary Clinton. Border control is put back into the center of political debates in many countries. Tougher border control is more popular in developed countries and it is not only about national security, it is also about the conflicts between the locals and migrants. In addition, all countries are self-centred and selfish, such behavior is natural and should not be blamed. Countries only take the actions that only bring benefits and enlarge the fears of all kinds of potential losses. This increases the difficulty for countries to cooperate together. The danger of the current global environment could distance the relationships between countries and make countries more self-sufficient but slow down the growth speed due to the shrinking PPF caused by the reduced trades.
