All over the world, wherever there are capitalists, freedom of the press means freedom to buy up newspapers, to buy writers, to bribe, buy and fake "public opinion" for the benefit of the bourgeoisie.
The minimum wage is lower if you have a job where you can get tips. Your employer is supposed to pay the difference up to regular minimum wage if you don't make it, but that often just opens a conversation of "well, why aren't you working hard enough to get the right tips"
Wasn't tipping primarily exempt from the minimum wage because FDR had to get the support of the entire democratic party to get his reforms passed, and the southern Dems refused to vote for anything that would make them have to pay black people. So tipping and agricultural labour was exempt from minimum wage laws, because otherwise the new deal would have gotten blocked by the presidents own party. And FDR figured that there wasn't enough of those labourers to kickstart a revolution by themselves, so he agreed to it.
