I believe Elon was saying 90 percent of government employees are not showing up at offices weekly now. Is it possible, that many of these employees do not even exist, and their paycheck is all just going to enrich a handful of insiders?
Thus, demanding that everyone shows up to work would be a means of calling them out on their fraud.
Definitely not a crazy take. I think it'd be hilarious if we found out that the government was run like Amway.
