There is little to no chance of Melenchon becoming Prime Minister or having any ability to enact this tax.
However a marginal tax rate of 90% on income over €400k is well above the upper-middle class and would apply to only the wealthiest families, most of whom would still have other avenues to minimise the tax they actually pay.
I totally appreciate your sentiment and generally agree, but with the caveat that the problem you’re facing is not just a problem with this current election, but an inherent issue with your electoral system.
