See, you just removed the problem and put it few step higher up the chain. You didn't resolve it, you just hid it under the carpet. Instead of taxing the company directly, you taxed the CEO, who in turn will simply take out larger dividends/increase their paycheck, which will decrease the company's operating budget, so they will have to increase the profit margin via either a price adjustment or a decrease in quality. The same thing happens, you just made the cause removed from the result by a couple of stages.
I don't know what you mean by "taxing CEO's proportionately", that doesn't mean anything. Proportionate taxation would be a flat tax, everyone regardless of income paying X% of what they make - that's a "fair share". I think you will find that this approach would have the opposite effect to what you intended - as it stands, the top 50% of society accounts for a *staggering* 97% of all income tax revenue. Out of those 50%, the top 1% pays 37.3% of the total, which is *more* than the bottom 90% *combined*. In all factuality, if the bottom 50% of taxpayers just *didn't* pay income tax *at all* and the IRS coasted exclusively on the top 50%'s contributions, tax revenues wouldn't even notice the dent. Food for thought.

I'm not saying that everything you believe is crazy, what I am saying is that the way you're trying to achieve your goals is destined to fail, and has failed repeatedly, for very predictable reasons. With that said, you're entitled to believe whatever you want to believe - beliefs are faith-based, not fact-based. Me, I just look at the numbers.
