Progressives as a whole are not white supremacist, white supremacy is antithetical to what progressiveism stands for.
Well then tell the people progressives rally around to represent their views to stop making statements that are inherently white supremacist in their roots and to stop being the single largest roadblock in politics to actually putting the policies of equality you claim to fight for into place. Every time someone proposes removing race and sex as a consideration for anything (since it is by definition discriminatory based on racist and sexists beliefs) progressives are the first and loudest to oppose it.
The nonsensical beliefs that those in the higher parts of political hierarchies have led to things like Bernie "whites don't know poverty" Sanders.
Potentially, what it may effectively do is force blue states to reduce their taxes in line with red states and decrease their state budgets. This will mean lower provision of social services to the whole state population... mostly of course disadvantaging the worse off.
It's also more complex, because some benefits are paid by the federal government, and the blue states being hit more tend to be major net contributors where red states are net claimers. Thus what it may effectively end up doing is facilitating more subsidy from successful blue states to less successful red states. One thing to bear in mind is that perhaps red states have lower tax rates BECAUSE blue states de facto subsidise them.
I don't mind the principle of redistribution ideologically, conducted evenly and fairly. But the political nature of selectively targetting Democratic voting states ahead of Republican is pretty dirty.
The reality due to the old system is we actually have no idea who's effectively subsidising who. California is by most appearances a net drain due to its social programs, but due to the old system on paper it looks like a net contributor due to the fact the money that would have been transferred to it never left in the first place. This is why despite already having high income taxes it's already in a financial pinch, and no longer being able to screw over the federal side of things is something that, while no in their interest, is in the interest of states like Texas.
Though one bright side is now those maps of the US that show which states contribute more then they put in vs those that don't will finally be accurate for once.
As a point of order, everyone with a salary (unless below an untaxable threshold) pays income tax. What happens is that they also receive various forms of state benefits which offset the income tax; for about half of households, this ends up being more than their income tax. The government just simplifies the maths to work out the difference so only one transaction needs to take place instead of two - but technically they are still paying tax.
Were the $10k threshold for the federal-state deduction not in place, for instance, the poor would actually lose from this, because their tax burden would increase, whilst their benefits remained static.
At the end of the day it doesn't really matter that it's all just a simplification of things or that it doesn't change much, given that the tax plan has benefited countless in the working class due either to minor increases in tax returns, minor increases in wages (like at Walmart for example) or one time bonuses, and many a combination of these.
Sure it ain't the tax man going away for good, but given the realities of governance it's not exactly something that was going to possibly turn out much better then it was.
No, modern progressivism is based on the notion that historically white men were able to gain for themselves advantages in economic, social and political power through whatever quirks of history and circumstance. These advantages, although no longer extant in legal form, persist through things like societal attitudes and hereditary wealth. These lingering advantages damage a meritocratic system, because non-white men of equal capability have a harder job getting equal rewards.
Yes and this belief doesn't pan out when put into the trials that is testing in reality. Even ignoring the outright historical ignorance of it by pretending that all white men where the 1% when the reality is white men where working the shittiest jobs in the West because men where the only ones to do it and there wasn't a noteworthy minority population to do it with them outside of the South and major Northern cities, it also ignores pesky problems like the fact that when whites started moving from lower to middle class, we didn't do it alone and Asians, despite facing literally every single barrier blacks did without anywhere near the political support, did the same. The reasons blacks stagnate (and let's not lie and pretend that there's any other race that people think about when dealing with this, since none have the problem of being left behind whites) is because of their culture, which has a defeatists attitude, actively discourages behaviour that will lead to success, ostracises success and a whole slew of other problems.
And it isn't even an inherent problem to black cultures, it's specifically one of African Americans. Haitians, Jamaicans, those of Somalia, they don't stagnate, their lot in life has improves considerably to the point it's a matter of when, not if, they catch up to whites, in fact Somalis on average do better then whites as it stands.
Blaming all of societies ales on white men because the exceptionally few in power in the West in the past where of the same skin and sex, even ignoring the inherent, overt racism and sexism of that line of thinking, not only ignores the problem, it dooms the problem to persist because no focus or attention goes on the real problem: African American culture is the near totality of the problem and until it changes to breed the same type of success every other group sees, it will remain where it is. This is why middle and upper class blacks tend to hold very low opinions of wider African American culture, why they are so critical of it, and probably a factor into why many are Republican despite blacks as a whole being overwhelmingly Democrat.
