I'll give her a lot of credit for addressing it, and talking about it.
What kind of kills me is the just incredible double standards here, and it's not just with our right wing friends. Just for example, in the 2016 POTUS primaries, every Republican ran on $trillions in tax cuts, and also as a fiscal conservative, worried about the deficit. Our 'media' largely overlooked the absurdity of those positions. How would they pay for it? No one knew or cared. Trump said he'd cut taxes by $10 trillion, balance the budget, expand military spending and not cut a dime from entitlements. He's president! Bottom line is as long as you don't threaten the plutocrats, no one cares much about your policies. All that matters is those precious tax cuts for the donor class.
AOC makes a comment clearly aimed at the working class, and she's pilloried, in large part by mischaracterizing her position and her priorities. If she said tax cuts pay for themselves, and trickle down nonsense, we'd hear cheers from these people, although it's a lie.
I don't really get it. I don't agree with some of her ideas, but I appreciate her focus appears to be genuinely on the bottom 80% or so and not the donor class.
