You can't talk about top rates without also talking about where they kick in. Italy's top rate of 43% kicks in for everything over 50k euros. The 50k feels a bit low to me, and maybe 100k euros would be better. 90% of everything over 5M may work, but then you run into another problem where people that rich are not bringing home a salary. So you lower where it kicks in and then just impact the working professionals, which also isn't who you really want to target. And if you do want to target those working $500k+/year, removing the cap (176,100 this year) on SS payments is probably a better path. So now we're back to the ultra-rich where you need to first think about taxing dividends as income without hurting retirees, and second think about some wealth tax. It could be small like .2% on everything over 5M or something, but it would actually put some tax burden on the people you're trying to put it on.
