And even in the paper that your liberal economists put out advocating raising taxes they admit the following: "Of course, increasing upper income tax
rates can discourage economic activity through behavioral responses, and hence
potentially reduce tax collections, creating the standard equity-efficiency trade-off
discussed in the introduction."
What they're admitting is that there is a natural response to higher taxes and that response is to move capital into investments that aren't taxed at the new higher rate.
Hahahahahaha. I'm just guessing, a Nobel in economics might not be in your immediate future.
Note "potentially" and "behavorial responses." It's not an economic dynamic, it's a confidence thing, akin to the consumer confidence index, which is FAR more of a concern, economically.
But it's largely a moot assumption. Investment is driven by opportunity. Period. So even if investors are slow on the draw, they will not leave low-hanging fruit dangling too long, if for no other reason, others might snap it up before they do. In the end, little if any real opportunity, is ever left unfunded.
Someone always gets after it.
