Communism is a failed plan and always will be.
The power TO PLAN is POWER nonetheless and the MORE POWER someone is given the MORE POWER they CRAVE!
An old classic deals with this issue brilliantly:

Government is an agent of force. Government is essentially a military agent of force.
Government can be a good thing if you limit it to its beneficial function of protection from invasion, But unlimited government is the most dangerous and deadly agent known to man especially to it own citizens. Government “social programs” is an oxymoron.
Government “social programs” should read “social pogroms”. The Fabian Society, the genesis of modern-day fascism AKA “progressivism” was not at all averse, for example, in sharing their love for mass killing in the name of better productivity.
Absolutely not true that planning always fails. You think that companies products fall out of the sky or by letting each employee do as they wish?
It require tremendous planning and execution to produce a smartphone, an airplane, a car, a chip, a skyscraper...
The problem is not planning, the issue is whether or not the ones that do the plans are responsible for results. Politicians and bureaucrats invariably get to keep their jobs and power regardless of whether their plan is a success or failure.
