I think you're blaming capitalism for a bad incentive structure internal to companies. Yes, many decisions are made to further the interests of the stakeholders of the business, and many of these things damage the business itself. But without paying people in stock, this problem largely goes away (not that improving executive compensation is so near-perfect that one change makes it immune from agency problems or conflicts of interest -- clearly other things need to be done).
