It's not that simple. Of course, the direct effect of corporate taxes is mostly on the wealthy who own most of the stock but that's not necessarily the group who gets most of the wealth--more on that below. Even in terms of direct payments, wealth isn't the only important factor. As significant is a company's willingness to be creative. I have never seen a corporate tax scheme that's ungamable that doesn't involve giving the IRS more discretion post-hoc in applying the law nor is one feasible in practice given the resources a company tends to devote to minimizing a multi-billion dollar tax bill. So we have the perverse situation where, to a significant degree, tax creativity is a productive economic activity and belief in adhering more closely to the spirit of the law of punished with higher taxes.
As for the economic payers. Consider what happens if we eliminate corporate taxes: The company has more money. It can use that money in three general ways: Lower prices, raise pay or return it to shareholders. In a company with little competition, the optimal calculation is fairly simple. Does the additional return enable new entrants at current prices? Do we have employees who could leave and create competition and to what extent does the additional cash-flow make it more likely? In a competitive environment, the right answer is based on the sensitivity of profit to talent, the sensitivity of talent to pay increases, and the sensitivity of consumers to price decreases.
Given this different factors, what's the empirical answer? It varies based on circumstance and no one can say definitively. Here's an example of one attempt to answer based on variation in European tax rates that suggests that 49% of the taxes are paid by workers: http://www.econstor.eu/bitstream/10419/51691/1/66322666X.pdf.

It is somewhat the same as raising pay, except is it not true that the average worker's pay has been flat for many years now (even those employed by corporations" while executive pay has drastically increased?
And I personally don't think the harm is in what percentage of the profits is paid to them per se, I think the more harmful aspect is the perverse incentives that are created when executive compensation is tied to short term corporate performance.
You're absolutely right about where the risk lies. That's why large shareholders have become increasingly concerned about alignment. CEO pay is increasingly in equity and they are subject to minimum equity holding requirements and clawbacks. I'd like to see larger minimums relative to their equity compensation but in the grand scheme of things this is a small issue.
It's also worth noting that short-term investors are a greater threat to long-term focused decisions than pay incentives. Most CEO's aren't actually foolish enough to risk destroying their company for more money in the near-term. They like their jobs so what does terrify them is an investor demanding more leverage or adopting a riskier strategy on pain of advocating removal or a hostile takeover. When Chuck Prince said he couldn't sit down until the music stopped, he wasn't worried about a smaller bonus but about posting lower profits that would have led to calls for his removal. "There was a merchant in Baghdad..."
Yes, given executive compensation trends, I wouldn't be surprised if executives would get a disproportionate share. That's largely irrelevant to understanding the aggregate impact. At large corporations, CEO compensation is usually less than 0.1% of profits.
