But regardless, silicon valley workers get equity as well that is taxed as capital gains - some times that makes up a very large proportion of their income. This is doubly true with equity from start-ups that might entirely be taxed at long-term capital gains.
But the point stands - what's the cut off. Sure, the guy making $40k is different than the billionaire. What about the guy making $500k? $1M? $5M? Now we're in CEO territory. Are CEOs "workers"?
The argument just doesn't hold water.
