The disagreement would likely persist even if it was $5M. I haven't heard anyone object to the issue because of its price. The US government spent $4T last year. So yeah, an extra $72B does seem like a drop in the bucket.
Looked at from the deficit, I suppose. Though I'm not persuaded by arguments based on what extra funds could do; there's a lot we could do by just rearranging the already ginormous amount the government collects. It's not going to happen, though.
