> I think it would be fair to characterize them as broad based taxes

Tariffs are broad based regressive taxes, falling predominantly on the lower deciles of the income distribution.

The OP seems to be proposing broad based progressive taxes. However the place to start first, politically speaking, is raising taxes the 10th decile.

Yeah, but that also contains the core customer segment for buying representatives, so probably not. We'd like to protect that market.
