Biden's infra plan was $550bn in new spending, which was offset in only $50bn of new revenue and $110bn of spending reductions. So, on net, it was massively inflationary and toasted the budget.

That was just one proposal with half a trillion.

Would you care to provide a citation for that?

According to any of the reporting I can find, the Inflation Reduction Act: "This bill would raise $737 billion in revenue while spending $437 billion. The remaining $300 billion would go toward deficit reduction." [0]

This is pretty much the same story with every major policy proposal from the Biden administration. They all included plans to cover the expected costs.
