Umm, excuse me sir. WHAT METRIC? Did you just pull it out of your ass?
Also what do you mean by scarcity? Because if your talking about famine, that's a environmental issue. Can't fix nature. But this is been fixed by efficiency and interdependence in the modern day.
Corruption is, and always has been, a huge problem in communist and post-communist societies. Communist administrations are objectively some of the most corrupt, by any metric, for the reasons listed above and more.

https://en.wikipedia.org/wiki/Corruption_in_Cuba
https://en.wikipedia.org/wiki/Corruption_in_North_Korea
All of these countries score very poorly in the CPI, or the Corruption Perceptions Index. Sorting out any administrative issues more often than not requires greasing multiple hands - the more communist the country is, the worse it is.

You will notice that nearly all of Europe and North America score very well on the CPI. Post-communist and communist countries not so much.
I was also unaware of environmental issues that crop up suddenly, prompted solely by regime change. Funny how that works.
By "centralized communism" I'll assume you're talking about the USSR here. Yes, they had a centralized economy, and the inflexibilities of it led to their eventual downfall. However, you have to consider their conditions and why they originally had a centrally planned economy. This was a country that went from a rural agrarian society to a world superpower in less than a century. Also, "centralization" is not exclusive to communism. If you really wanted to, you could have centralized versions of other economic systems like capitalism. Statism, "centralization", etc. are all separate from economic systems. They are modifiers, not inherent.
I am familiar with how the U.S.S.R. grew to be a superpower in such a short time frame - by way of annexation and exploitation of its immediate neighbours, including Poland, my home. It's also fairly easy to feed a growing population if you systematically murder large swathes of it, as was the case in Ukraine.
yeah... and anarchist communists exist.
I believe you would enjoy this person.
...person?

And a communist? That's an oxymoron.
Jokes aside, me not being a huge fan of the government does not make me an anarchist, and I do not feel kinship towards anarchists. Government is necessary and has very specific, limited functions. What I oppose is the government overstepping the boundaries of its authority and intruding on the private lives of the citizens. There's a big difference.
Bullshit. First off they don't have to pay you what your worth, and again, I highly doubt that a walmart employee is worth 12.50 an hour for front end.
You're right - they're worth
less. Amazon has even made huge strides in operating stores with *no* front of house staff, only warehouse workers, which too can be replaced by machinery in many cases. Their contribution is just not that valuable, and there's an ample amount of people looking for jobs in retail. If you feel unsatisfied with your wage, there are 10 other people with the same skill set available. The pandemic is a special circumstance because the government is actively disincentivising returning to work, so there's a bit of a labour crunch. For now.
