I mean incentivizing them to invest it into things like public works and other beneficial things, but I also expect that that would go about as well as the current tax incentives do. It would be the thing that requires the least effort possible from the government, though, which I think makes it the most likely to actually occur. Actually taxing them more is pretty much a pipe dream.
No worries, like I said in my edit, you fixed it while I was writing my comment. I’m just leaving mine unedited for the extra info.
