How to say "capitalism" in Japanese

• キャピタリズムCommon
  nounThe loanword, transcribed from English 'capitalism'; it names the same economic system as 資本主義. Its katakana shape keeps the ring of the English original, and it suits writing that wants that echo.
• 資本主義しほんしゅぎCommon
  no-adjectiveThe Sino-Japanese term, built from 資本 'capital' and 主義 '-ism'. It covers 'capitalism' as an economic system with no special coloring, and is at home in textbooks, news reports, and political debate.
  共産主義きょうさんしゅぎが崩壊ほうかいしたことにより、今いまや資本主義しほんしゅぎが「世界せかいを支配しはい」しようとしているという非難ひなんを浴あびている。↗

  As communism has collapsed, capitalism is now accused of trying to "dominate the world."

Both words mean capitalism, the economic system of private capital, so the choice is one of form: 資本主義 is the Sino-Japanese term, while 「キャピタリズム」 is the English loanword, carrying the ring of the original.
