executive action by committee doesn’t work.
Is there actually any evidence for that? Isn't that basically what they have in Switzerland? And they are one of the absolute richest countries in the world.
Above the CEO is usually a committee called the board, which govern all stock companies, and by far the most successful big companies are stock companies.
Companies run by a CEO without responsibility towards a committe (board) have much higher risk of doing something incredibly stupid that ruin the company. And can't be removed no matter how incredibly stupid and harmful they are to the company.
For example as we see with Elon Musk and Twitter. Donald Trump and his Casinos. Pillow guy. Michael Dell.
Funny enough also Steve Jobs at first, but then taken in to rescue Apple successfully later.
