Already any discussion that centers around "capitalism" is deeply problematic as it invariably takes enormously complex sets of laws, conventions and behavioral attitudes that varies materially (both historically and regionally) and forces it into a binary yes/no universe. You can't solve complex problems with random hammer blows on each others heads.
All of the constituent components of what we term "market democracy" must be examined not as what they say on the label, but what happens in practice. Just as a simple and single example: when politicians routinely enter revolving-door appointments to serve private interests how can we even pretend this is a feature of "capitalism".
The true underlying behavior is cooperating private gangs marauding the commons. It doesn't matter if it happens in ultra-capitalist US or "communist" China.
