"Rich and paying no income tax" -> largely the top end of the top end. The vast majority of rich people pay lots of income tax.
I'll go out on a limb and guess that you land in the category that most Americans consider rich, but you think attention should really be directed towards the ultrawealthy. Totally reasonable and capital gains obviously needs to be the center of that discussion, but let's not try to get there by just moving the line of what "rich" is and helping people delude themselves into thinking $300k+/yr is middle class.
