Capitalism by far.
As stated many times in this thread, Communism doesn't work unless the government is totalitarian.
Same with Socialism.
Also, mixing in Socialism is never a good idea.
Take Germany for example.
They use capitalism for their economy, since thats what works. However, they have socialist laws, such as each family is only allowed to have a certain amount of televisions, laptops, etc. They don't even think a family should have one for each member. As a result, they are very totalitarian. They hate homeschoolers because then they can't be indoctrinated from an early age, much like laws in the USA become more and more restrictive against homeschoolers each year. They won't allow anything speaking against the government, there is massive censorship of news, etc, and the government is essentially an aristocracy, just like the USA is becoming.
tela's simple breakdown of economic and governmental beliefs:
Communism: Doesn't work. Take Russia and China: over 100 million deaths.
Dictatorships: Hitler. enough said.
Aristocracy: British Empire (with input from king), was one of the most brutal and sadistic empires of all time, but this history is not taught. simply google 'british atrocities' and you will be disgusted by how censored everything is these days.
Socialism: sounds amazing, but as there will always be people who work, and people who laze, it will never work except when freedom is taken from the people.
Capitalism: used to work until the USA elected socialists who ruined it over the last 50+ years.
back in the early 1900's, the the largest oil company in the world was forced to split by the US government. Two of the companies, Exxon, and Mobil, have rejoined to create a monopoly in many areas of the country again.
Comcast is a monopoly.
Verizon is a monopoly.
AT&T is a monopoly.
the list goes on and on.
But these monopolies have bought the votes of most of our government, and thus nothing will ever happen to them.
Tl;dr
Capitalism rocks, Socialism leads to concentration camps, same with Communism.
