the idea is to make food less expensive, because it is a stress on a family’s budget. Not sure how family farms will do that.
I can see a case for a safety net to protect against natural environmental conditions, such as a drought. Farms should not be protected against competition.
And we need a stable $ because monetary deflation is another big problem. That should be dealt with directly as it affects the whole economy and not patched up just for the farmers.
Everything is heavily regulated. You want to irrigate your field, fill out an environmental impact report. You have to have your water regularly tested to see what's in it even when it is right out of the well. Where's the runoff going to go? What is in the runoff? It better not go into a creek...
Want to fertilize your field, see above.
It goes on and on, and costs a small fortune to comply with. Make a mistake and get fined out of existence.
