If this works it will be a case study for all MBA training.
Twitter is probably an extreme case, but people ought to realize that many companies and many industries have too many employees. There is the old formula that 20% of the workers do 80% of the work. That's true almost everywhere. And think about government! Probably very much like Twitter: fire 99% of government employees and nothing much would happen.
If this realization sinks in ... we could see tremendously reduced levels of employment. Work gets done. "Stuff" is produced. And about 80% of the population sits at home with nothing to do.
Once can debate precise numbers, but I think we are rapidly headed to a future with greatly reduced need for human labor. Plumbers will be fine. Certain job categories will be fine. But a lot of the workers out there will not be needed and that's going to be a huge problem.
This is really no different than the federal govt. Im willing to bet at least 70% of the federal workforce could be terminated and the country would be fine. Perhaps it would run better and we stopped spending maybe turn a profit.
