I want to be fiscally conservative, but it's nonsensical without addressing the elephant in the room - inflationary policy. Spending money on deliberate projects is necessary to alleviate the nasty effects of the previous trillions that were, and still are, being given away to the banks. Focusing on the few scraps that the government throws to the people is a red herring.
Also the Democrats' hands are tied, not being able to pass substantive non-financial legislation like HR1. Budget is one of the few things they can use this "reconciliation" to push through without filibuster, and so they're trying to use spending to solve everything.
