You can have a capitalist dictatorship…
South Korea was a dictatorship and had no voting system until 1986 or 1988.
Republic of China (Taiwan) was a dictatorship and had no voting system until 1996.
South Vietnam was a dictatorship until the North overran them.
Yet, only the propaganda that used by the U.S. government tried to justify the reason to help these dictatorships(the truth is all about anti-communist, enemy’s enemy is my friend) claim those governments were "democracy and free".

P.S. You have to look deeper on the issues.
For example,
South Korea got huge amount of aid (during 50s~70s) from the U.S. who is the richest country in the world. The U.S. also stationed lots of troops in South Korea. Thus the South Korea did not need to spend a lot on their own military, instead they put majority resources into economy development.
North Korea, on the other hand, had next to 0 economy assistance. All Chinese troops pulled out just a few years after the Korean War. Thus, North Korea put majority of their resources into military instead of economy because they were on their own and they believed the hostile U.S. could attack any time. On the top of that, the U.S. and all its allies placed sanction/embargo on them.

We still debate communism and capitalism because communists believe that communism was not properly implemented in those countries – and they are absolutely right. The problem is that communism can NEVER be properly implemented; human beings are self-interested, and a ruling elite will always take the place of the bourgeois. Indeed, even Lenin suggested that the elite knew what is good for the masses, an affirmation that goes against the spirit of Marx.

With regards to Marx, his theory is utterly fascinating. Regrettably, Marx did not predict that rise of corporations, the welfare state, and unions – these three modern entities nullify many of his predictions, which were based on the classical economics of Adam Smith.

Hope this helps. Have a good one.
