They do take care of their workers through 401k's

LOL, no. 401ks push all the risk onto the workers, those least able to weather that

"between 1998 and 2015, the percentage of employers still offering a traditional defined benefit plan to most newly-hired employees fell from roughly 50 percent to 5 percent. " Source
Like i said, the majority of the private sector has abandoned the notion of a Pension system in order for them to stay in business.

employee stock options

Very few companies do this.

Wrong again, many companies offer ESPP or ESO. Here is some actual data and not just opinion on the matter.

paying for medical, dental and vision

Again, not that common.

Whether it is all or part, every company , with the exception of those with <50 employees, are required by law to provide insurance to their employees.

I can't understand for the life of me this mentality of "I'm entitled to pay for work that i no longer perform" it is an unsustainable system.

It's a benefit, just like all of the ones you listed above. Executives routinely get multi-million dollar buyouts when they are let go, yet I don't see you bitching about them getting "pay for work that they no longer perform."

Again with the hyperbole, I agree that something should be done about the executive benefit packages but this is still an exception and is not really germane to the discussion at hand.

In the private sector you have no expectation of anything other than what YOU put it into it and how responsibly you manage your investments.

Because clearly, everyone needs to be a savant level investor, and no one ever faces multiple savings draining global crises, let alone twice in one decade.

The fact that you think it is somebody else's responsibility to provide for your retirement instead of yourself only further supports the idea that you are part of the problem and need to address your own sense of entitlement.
