It does work if you rely on actual relevant data. Disparity is a terrible measure, especially when you consolidate the entire world into one pot. China has higher taxes than the US, and far worse inequality as well as far lower median incomes. Europe has substantially higher taxes and cost-of-living than the US, but lower median, PPP-adjusted median, and median post-tax post-government-transfer disposable incomes than the US. When you compare countries by their tax rate compared to what the average (median) citizen ends up with, it does not seem to be the case that higher taxes result in greater personal financial security. Frankly, whether lower taxes results in more billionaires is irrelevant to the question of whether it increases the quality-of-life or economic security of your average person. Imagine pointing at one of the richest societies to ever exist (across all quartiles) as an example of how bad its economic policy is.
