Key question about tax reductions

Although I've been voting in all general and midterm elections in the past half century, during the last 35 years I've carefully scrutinized them, discovering that Democrats usually proposed tax increases for high income earners and Republicans consistently opposing them.

Tax reductions on high income earners won out. The result has been deficit spending, an unprecedented increase in the national debt, and the decline of the middle class.

During this time income inequality between the rich and poor widened and now the greatest gap in world history.

But this begs the question: Why are tax reductions affecting the wealthy so toxic when their principle is untouched, leaving their already accumulated fortunes intact? Don't taxes apply only to recent earnings?

Which previous State of the Union speech has ever explained this small detail to the public? What am I missing?
