But are you purporting this agricultural system as effective?

It isnt their agricultural system, I would suggest you reread the whole thing because you've missed the most important aspect of what taean means. It means a collaboration between organized local labor and wider democracy, overseen by special interests such as the woman's league.

Further I assume you bring that no fact up as argument that collectivist style policy is effective and happening, I would argue it is ineffective and still only a farce under authoritarianism. Else why would nk receive aid, and experience famine?

Why would you argue it is ineffective? Studies show the cooperatives work better than privately owned businesses. Also you haven't established that the dprk is "authoritarian" any more than any other state.

They experienced famine after the collapse of the USSR, theyre doing fine on food now.

Lastly, I don't need to know the economic history of the country to know where they are now. It's not propaganda that got me here, it's their own words and reports.

Well, you should. They tried to liberate the south when the US and US puppet dictator were killing tens of thousands of protestors. 20 percent of them died and all their infrastructure was bombed. After the war they did better under a socialist economy than the South until the US massively subsidized the South and the USSR collapsed, cutting off trade because of sanctions from the people who committed genocide on them (the US)

I would like to know what "own words and reports" you're referring to.
