Get real, this is an amazing boon for lobbyists. Members of congress would not be able to gain experience at crafting legislation and dealing with the entire shitshow process at the federal level. Lobbyists can still be lobbyists for life.
On top of that, this significantly weakens congress's position when raising funds for elections. They've got to dance to the right tune quickly, they can't slowly ramp up a career and build a brand. With their bargaining power lowered...ugh.
America is probably going to get totally fucked now. And no, not necessarily because of this. But this policy proposal is the best Trump could come up with? This isn't even half-baked, it's fucking flour in a pot and he's calling it cookies. How can this be called a contract.
