There is no legislation preventing any employer from offering or providing said benefits, but there is the reality of the system in which they must operate. In the no-holds-barred, winner-take-all world of concentrated wealth and power many who would operate more empathetically would probably not survive long enough to receive the gratitude of their employees.
The examples you offer are all of mega-corps. The ones polled in this report, though quite wealthy, are not in the same league. They are not part of "the planning system" and cannot control and manipulate the environment they operate in. And Yunzer your comment only confirms the point I'm trying to make, because small business owners are not part of the planning system but must somehow survive in "the free market" where self-exploitation is a way of life, and though abuse or exploitation of their employees may not necessarily be intentional, it is often a necessary fact.
Suppose you saved up a nest-egg just sufficient to open that small business you always dreamed of and to make it work you had to hire a few employees. Since the success of that endeavor probably would mean a healthy and constant dose of your own self-exploitation it's a safe bet you'd hire those people for as little cost to you as possible, not out of spite or malice or greed, but out of necessity. Or you could go tilting at windmills and become the Jesus of Nazareth of Water Street, Anytown, USA, and the next day take your place once again as an employee and not an employer. Your enlightened entrepreneurship would have the same effect as a fart in a wind storm.
But this is all beside the point of my original objection to your comment. And that is, I believe you have overly generalized a large swath of people, and consequently reached an overly cynical conclusion. Maybe I'm wrong. Daily false-flags, bait-and switches, and dis-information is foisted on us and this reported analysis is just another example. And maybe all those that were polled are so rehearsed in all their roles that they answer to maintain the PR chimera. But I don't buy it. So we agree to disagree. I'm not the enemy, and have always been an employee and not an employer. I usually agree with most of your postings and don't wish to engage in a drawn-out argument about a conclusion or a suspicion.
