curious how they came to that number. There's probably plenty of voters willing to cast a vote for $0.5M+ and plenty ready to cast a vote for $100M+. How was the line drawn?
"The top 1%" is a popular target for these schemes because 99% of people might be convinced to support it, since it won't affect them (at least not directly).

I think your assumptions are off, though; less wealthy people might not be "forced" into investment at all, but given the "opportunity" to pay off debt or increase/diversify consumption. In the end, the important part is the wealth transfer downward, wherever it ends up. No trickle, but you can pump it.
Arguably, there’s a disconnect where the people who lead civic organizations don’t have a great deal in common with the median member. They might be wealthier and generally more plugged in to power structures. They might not support policies that are in the best interest of members they represent, especially people who have a hard time representing themselves.
Anyway, if your goal is to get a policy enacted, it’s not enough for your policy to be theoretically good for the median voter. You need a winning political coalition.
