Meh.... whatever. I don't really have time to go over this. Complex issue. So I'll just put it here.

But “hoarding” has differing connotations, as collectivism in Soviet Russia demonstrated. Anyone who had extra grain and hid it in order to avoid starvation was labeled a hoarder.

The reason that Bolsheviks starved people was generally the same reason that Madeline Albright said that starving to death over 500,000 Iraqi children was "worth it."  It's a siege mentality that leads to preemptive wars based on tribalism and ethnic hatred. 

So if you're concerned about results like that where hundreds of thousands or millions starve, then focus on its source in tribalism and racism and ethnic hatred.  Its source isn't normal progressive ideas of the sort that gave birth to the eugenics movement or a "task force" on hoarding or whatever they're up to now.  Even if they're misguided, many are usually trying to be helpful and not masking a dead eyed form of tribal hatred like Madeline Albright's. 

  For example, its Soviet version.  Starvation included:

Genrikh Grigoryevich Yagoda (Russian: Ге́нрих Григо́рьевич Яго́да; 7 November 1891–15 March 1938), born Yenokh Gershevich Iyeguda (Russian: Енох Гершевич Иегуда) was a Soviet secret police official who served as director of the NKVD, the Soviet Union's security and intelligence agency, from 1934 to 1936. ....   Yagoda also supervised the construction of the White Sea – Baltic Canal using slave labor from the GULAG system, during which many of the laborers died.
   Yagoda was born in Rybinsk into a Jewish family. He joined the Bolsheviks in 1907. --Wikipedia

  Millions dead.  Hundreds of thousands starved to death.  Children too.  "Worth it."  Etc.

Interesting that people can still hardly deal with the topic of one of the main reasons that Soviet Communism and the starvation of millions came into existence:

...it is impossible to find the answer to the eternal question: who is to be blamed, who led us to our death? To explain the actions of the Kiev cheka [secret police] only by the fact that two thirds were Jews, is certainly incorrect."
   Solzhenitsyn, awarded the Nobel Prize for Literature in 1970, spent much of his life in Soviet prison camps, enduring persecution when he wrote about his experiences. He is currently in frail health, but in an interview given last month he said that Russia must come to terms with the Stalinist and revolutionary genocides - and that its Jewish population should be as offended at their own role in the purges as they are at the Soviet power that also persecuted them.
   "My book was directed to empathise with the thoughts, feelings and the psychology of the Jews - their spiritual component," he said. "I have never made general conclusions about a people. I will always differentiate between layers of Jews. One layer rushed headfirst to the revolution. Another, to the contrary, was trying to stand back. The Jewish subject for a long time was considered prohibited. Zhabotinsky [a Jewish writer] once said that the best service our Russian friends give to us is never to speak aloud about us."

If you're concerned about totalitarianism and people being starved economically then focus on the ethnic hatred that usually gets the ball rolling.  American and European progressives are not the same as Jewish Bolsheviks or Madeline Albright being motivated by ancient "not worth a Jewish fingernail" ethnic hatreds looking at others starving to death and thinking: "This is worth it."

Everyone has had their own version of that.  Islamic/Dhimmi, Talmudic/goyim, Nazi/lesser race,  Christian Zionist/exceptionalism  ... etc.  But there's usually only one that people are generally blind to, make excuses for, or call people names like "antisemitic" over.
