Penneys, Macys, and Walmart, all from the meme above are all in the process of closing stores. Sounds like their CEOs are making great decisions.
It's always a possibility. There's no guarantee that a CEO will always make good decisions, but there's also no guarantee that even consistently good decisions can inure a company against a changing environment and competitive pressure.
On a broader note... it might be worth considering the sheer volume of important decisions made by CEOs on a daily basis. As a manager, I make key decisions maybe once a month, generally around prioritization and intake of work for my team. My Director makes key decisions on the order of once a week - not just in terms of prioritization and work intake, but also in terms of investments and strategic direction for our department, with consideration for the impact of those decisions to the long-term health of the company. My CFO makes multiple decisions daily about prioritization of work, strategy, and investments for both long term and short term objectives, affecting the work and resources of a large portion of the company, and balances competing objectives and strategies across a wide variety of topics that all interrelate. My CEO does all of that and more, every day, for the entire company, across all aspects of our business.
In short, I make important decisions on behalf of my company maybe once a month. My CEO makes important decisions on behalf of my company maybe once every two hours.
