True that! A lot of legislation passed (if you're in a country that actually believes in passing legislation) is often incomplete. Even within a capitalist system there can be some degree of a solution achieved. Austerity has thrown a wrench in that but we've seen that with enough pressure the state can occasionally help.

Perhaps (I'm in the US so my ideas may not apply elsewhere) instead of additional subsidies to agriculture we could reallocate the ones were already giving out to more nutritious crops. Corn gets far too much money for example, that's why it's in literally everything here. It's so cheap it's more cost effective to process the hell out of it and turn it into something else entirely over just growing something else. Likewise, dairy gets a ton of money and we waste so much of it.

That money could be given to a broader variety of crops, alongside some sort of legislation to make the disposal of perfectly good food either outright illegal or with heavy fines involved to the point that it's more profitable/less costly to just sell the food. Hell, tax breaks for giving it away too. Because if there's one thing that will get rich dicks on board it's tax breaks. Maybe throw some additional incentive to move away from pesticides and monoculture as well
