The US is centrally planned to some degree, just in different ways and by different interests.

I suspect the interests/actions of lobbyists for certain companies/sectors had significant influence on things like taxes, and is a type of central planning.

It's different than most central planned economies because there are two entities operating in parallel (a quasi-private corporate state in addition to the usual government state), but I'd say it's still centralized/planned, even if it's not the state/government doing the planning.
