I'm not seeing your point here? it IS still a sellers market, and companies do pay for those things. So its still a savings for them. As for a 'drop in the bucket', I've seen companies try to save money by buying cheaper pens. So I'm sure cheaper rents, utilities, perks, etc. will be considered...
edit: grammar
Just as employers can now access remote employees anywhere in the world, employees can access any company hiring remote.
I especially like the "employees can access any company.." part, as it gives me a lot more options. Up till this now, it was basically only SV companies and small startups that were open to it.. So I'm looking forward to being able to cast a wider net next time I need to look for work.
They still save on janitorial, security, utilities, rent, etc.
So I fail to see how companies don't save money. And from what I've seen, companies will consider anything that saves them money...
