I work for a large company. I suppose the CEO could decide to fire a huge percentage of employees tomorrow without regard or understanding of their actual job duties and in the very very short term brag about all the money saved since they no longer have to meet that payroll. But in a few months the wheels are gonna start to fall off.

Most of us in the US know that when we go into any government office, there is one person that really knows what's going on and does the work, while numerous others (standing around or playing on their phones) are there because of their relationship to some politician who owed them a job. That is IF they even come into the office.
