Would you also argue that when companies need additional funding during hard times or to expand, the employees should be forced by law to invest their own money into the company? With harsh penalties if they refuse?

If not, then it seems like someone else is taking all the risk but the employees are reaping all the rewards.

It would be great for me personally if my employer was forced to share his profits with me during the good times. But the reality is that during the hard times - when there's a global pandemic for example - he's the one who has to remortgage his house and max out his credit cards to make payroll, whereas I'm just a guy who can walk away with a month's notice.
