This only true in places that aren't environmentally supportive of agriculture. My family never had to buy vegetables. Granted we had about 2 acres of farmable land. We didn't sell produce, we harvested and froze until we needed it

Edit: Initial start up is definitely not as cost effective as buying from the grocery, but once you're able to harvest your own seeds, it's not that expensive to sustain your production

Assuming it used all the same tools and techniques, making only minor replacements of tractors for voluntary domestic labor .. I don't see why it couldn't reach averages in a similar magnitude. Given them larger plots where they could use industrial tools and they should produce about the same on average.

Eother way there attempts more self sufficiency are to be commended... So the I'm not sure of the point of the post really.

If we had a socialist style of market economy like Vietnam we'd produce more crops.

Also in a correctly valued economy we wouldn't have to subsidize farming.

Also subsidized industrial agriculture: "lmao let's grow nothing but corn in a pool of roundup ready corrosive acid"

"Here's your high fructose heart attack, double dipped in glyphosates, in a can. enjoy lol"

Where's that 4chan post where all the BLM rioters tried to set up a new community in Seattle or something. Then they had everyone give there skills and what that want to do in the new world, everyone was saying they can grow food. Then there was the crappest plot of veggies I have ever seen.
