Having locals who got paid to farm? The impact was dramatic. Paying farmers forced landowners to either invest in their land, or sell to someone who would.
Landowners actually started making MORE money from farming. They were more likely to keep land in farms than develop it.
My grandpa's neighborhood started growing high-revenue crops like fruits, vegetables, and nuts instead of low-ticket industrial crops. The food system became more responsive to consumer needs.
And, most importantly, young people could get a job farming & get paid real money for it.
They saved up for land & started their own farms.
Big landowners stopped forcing small farms out. Instead, they became incubators for the next generation of innovative local farmers.
