My POV
My own POV is that liberal democracy and capitalism overall are beneficial.
In my view, arguments for democracy includes no wars and no conflicts causing any battle deaths between liberal democracies (See Never at War and Democratic peace theory). Little democide, corruption, and few civil wars. No liberal democracy has had a large scale famine. More democratic nations have higher average self-reported happiness (See Liberal democracy).
In my view, arguments for capitalism includes the Index of Economic Freedom, one way to measure the degree of capitalism in different nations. More capitalist nations have less poverty. Note that also nations with high progressive taxation, like Sweden, can be very capitalist. See also the Ease of Doing Business Index and the Global Competitiveness Report. Due to globalization, poverty is rapidly declining around the world.
However, there are of course many opposing arguments and I have tried to include the views of both sides in order to achieve NPOV. I believe that the capitalist system must include policies redistributing wealth from the most wealthy, since it is easier for the already wealthy to gradually accumulate more wealth than it is for the poor to gain any wealth. Therefore, relatively high progressive taxation, wealth tax, and/or inheritance tax.
I strongly believe in the fundamental Wikipedia policies Wikipedia:Verifiability, Wikipedia:No original research, and Wikipedia:Neutral point of view.
