You realize immigrants do that ALL the time for their families, right?

What's your point? Please connect it to the context of this conversation.

It was in response to : [..] Plus when you land there, you won't be getting help or support. So toss all your support network for more space. For some that's reasonable, but for many it is not, and presuming that it's their own 'fault' for not moving is not charitable.[..]

It is just one more failure to come up with a robust solution to the problem here.

Immigrants land in places without a social net or help or support network literally 100% of the time. Often moving to places where language and culture and geography is starkly different from what they are used to reach for their best interests.

It is not the end of the world. To refuse to leave the cozy familiarity of ones social network is understandable only to those who feel the he same way.

Most immigrants I know leave their home countries and the coziness of familiarity for their children. And moving around America even temporarily is not the same as moving across oceans for a better quality of life.

Yes, all true, but let's not forget the overall context of the OP -- people's reactions to co-workers needing an extra day off. Deciding to uproot your life rather than take advantage of temporary company policies connected to the pandemic seems to be an overreaction.

That’s between employees and employers. My ire is directed towards those who claim that childless are free loaders being subsidized by the future generations and that having children is a sacrifice borne by them for society.

Employment contracts should be examined due to the extraordinary circumstances we are in and that would depend on the companies. I was only replying to specific comments that may or may not have anything to do with OP.

I’ve moved many times in my life to improve it.

Everyone sacrifices. If moving is your biggest sacrifice, consider yourself more than blessed.

Let's not forget the context here. The context is people complaining that their co-workers are having to flex their time, or take extra days off over what they normally would. This is not about someone improving their life, this is about making adjustments to temporary conditions.
