You can argue that all you like, but it is a ridiculous point. It's not perfect, but most of the time democracy works. This much is self evident.

If you are comparing the difference between having a company in charge of public health and a democratic government, you might as well compare the difference between a dictatorship and a democracy. Customers are not stakeholders in the same way that citizens are stakeholders.

When the public is angry at the government, heads will roll. When the public is angry at corporations, heads will glide down in golden parachutes.
