Communism has never been done properly, because it cannot be done properly.

Communism is an erroneous idea. It starts from a correct premise, that humans who have accumulated much wealth are able to use it abusively for accumulating more and more wealth at the expense of the others, and this positive feedback cannot be stopped without some kind of regulation.

However, the solution proposed by communism is an illusion that cannot work with real humans. The communist solution is to confiscate everything valuable from all citizens and put it under the management of the state bureaucrats, who supposedly will administrate it efficiently and in such a manner as to produce maximum benefits for all citizens.

The reality is that of course the communist bureaucrats are composed of the same people who succeed to become politicians or managers everywhere, i.e. those for whom the priority is to satisfy their own interests and greed, and not the interests of the entire society.

Therefore in all socialist/communist countries, those who were supposed to manage resources in the name of the "entire society" behaved exactly like the owners of those resources, so they lived like US millionaires or even billionaires, while most of the population lived in poverty, because all what their parents or grand-parents had in the past had been confiscated and now they were at the mercy of their managers, who decided unilaterally what they should be allowed to work and what they should receive to be able to live.

The only solution that could work would be the exact opposite of communism. Instead of centralizing everything, the production of at least all the things strictly necessary for living should be as distributed as possible, done by numerous small local companies, not by a few huge global monopolies.

Instead of having 3 producers of memory chips for the entire Earth, there should be at least 3 or 4 in every country. Similarly for any other industrial product.

Unfortunately that is extremely unlikely to happen because during the last decades everything has evolved in the opposite direction.

To continue with the same example, when I was young a large fraction of the European countries were still able to make integrated circuits and computer memories, even many of the East-European countries. But then one-by-one most electronics or computing companies have been bought or closed, until none survived. An important role in the disappearance of the electronics industries in most countries had been that of USA, who used various means of pressure and blackmailing to prevent other countries to enact protectionist measures favoring their internal producers against US companies, i.e. exactly what now USA itself uses against China.
