Democracy is “owned” by stakeholders, and those stakeholders are the people. So it makes sense for them to have a say in how government works.

A company is owned by shareholders, and they take all of the risk for the company. An employee shows up and gets paid, with none of the downside risk (their paycheck won’t go negative), so the employee isn’t a stakeholder. Therefore, shareholders make the decisions, not employees.

In some structures, employees are the share holders and thus help make the decisions.
