It's like taxing the rich. How many years.....decades have they been saying that? They don't really WANT to raise taxes on the rich, if they did, they would have done it already. For a time when Obama was president, they had a chance, and now, I'm sure they could pressure Manchin and sinema to vote to end the filibuster, but they don't, and they won't.
If the dems actually went through with their tax the rich agenda, it would piss off all of their donors and they wouldn't get all that money. So, they just throw that phrase around and try to use it to make the right look like evil rich greedy bastards, but they themselves are exactly the same as those "rich greedy repubs". They all hang out at the same uppity places, they all use the same tax loopholes, and hide their money from being taxed too much. They all get money shoved in their pockets by big business and lobbyists.
The dems like to talk a good game, but when it comes down to it, they are just like the repubs the claim to despise so much, which is why they never follow through on their desire to raise taxes on the rich.
