There's a lot of money to be had by making sure Americans are divided and not united against corporate interests. In addition to limiting corporate lobbying (including fixing the lobbyist/regulator revolving door), campaign donations, etc, I would really like to see more research into how media and social media influence polarization, and perhaps some regulation around social media curation.

It's less about the polarization and more about the dominance of the hydrocarbon lobby. In Europe it just isn't as powerful.

It's the same story with a few lobbies - especially gun manufacturing and HMO.

The most successful lobbies may favor one side but they are pretty bipartisan.
