[T]hat liberal world that emerged after 1945 led to one of the most spectacularly successful periods in human history. There was material progress. T… - Francis Fukuyama

The polarization has a number of different roots. The economic... fact that many working class voters have been left behind by the prosperity of globalization. ...[T]he more important division is a cultural one ...the feeling on the part of many populist voters, that they are not being respected by the elites that are running the country... [H]ere, all of the identity issues... play themselves out.

[L]iberalism is... a protection of human autonomy.

Then finally, there's a good economic reason for choosing a liberal society because among the rights that liberalism protects is the right to own private property, to transact, to engage in commerce, and therefore it is the basis of a market economy. Liberal societies like England and the Netherlands in the 17th century, were the leaders in terms of creating the modern economic world precisely because they respected property rights and trade. Even Communist China, when it opened up in... 1978, did so by adopting certain liberal principles. Deng Xiaoping allowed peasants to keep the fruits of their labor, and as a result of those incentives, quasi-property rights, agricultural productivity doubled in the space of 4 years, and in general, the most dynamic parts of this amazing Chinese growth story come from the private sector where people are allowed to buy and sell, and... in effect to own property. So even in a... politically illiberal society, economic liberalism has led to tremendous prosperity. So those are the 3 reasons.
