I point my finger at modern financial markets.

If you bought some stock, and were forced to keep it for atleast 5 years, the CEOs would have to behave a lot more carefully (=good for the company in the long term), than they currently do. With millisecond stock tradings, noone cares about long term future, because the stocks are sold and rebought and resold again and again many times by many trading houses and their financial products.
