> if they increase spending, you get more inflation, and then they have to eventually pay higher rates on their own debt
You can spend in a dis-inflationary manner: increasing production capacity, facilitating resource extraction, and generally anything that helps on the supply side of things.
But absolutely, given the current Administration and the Democrat agenda, this is anathema. If anything they would rather spend to destroy supply as much as possible, since this is generally what the SDG, DIE, and Green agendas consider "success".
A great example is the Inflation Reduction Act. The "green" portions were estimated to cost $390 BB initially, but are now estimated to cost $1045 BB (yes, over a trillion dollars), and this number will almost certain go up[1].
Not a penny of it goes to anything that would increase supply of what you'll need for the "green" infrastructure, it's all pure demand, the bulk of it EV incentives. You would have trouble coming up with a more inflationary plan if you tried.
