The problem is that taxes are never actually raised "fairly" or even at least proportionally. And the higher taxes rise, the faster the social split accelerates, with fewer and fewer (relatively) people paying first 40%, then 45%m then 50%, all the while watching their richer neighbors tax evading first at 30%, then 25%, then 8% then 1% then whatever comes after. I assure you, nothing motivates voting for literal Lucifer if he promises to reduces taxes even a tiny bit from the levels already reaching 50%+. I'm at the bottom quartile per my position and I pay 40% annually, my richer peers from top quartile pay something which would amount to around 22-24% annually from a higher gross too. Same country, same industry, same bands/grades. M for Motivation. I personally wouldn't vote for Lucifer at next election, but only because I do realize that he would simply lie about everything. But I do understand everyone from middle class who would believe sweet lies.

And while the notes above are my observations and thoughts, they are not something outlandish or wrong. Sociologists have also noticed this effect, it even has its own name and studies:
