Honestly this whole issue has become one big clusterfuck. It would take hours to even provide a high level overview of the screwed up food landscape.

Many, but not all farm subsidies are all kinds of fucked up.

Also, its unfortunate but the regulatory and taxation regime in the US (and in some cases this varies by area) favors megafarm producers in the US. While its still a better situation than China regarding food quality regulation, slowly but surely we are getting there.
