I don't know what "innovation, problem solving and creativity" you're witnessing. In my experience, at
some jobs, people will sit around desks and talk about things, but at others they definitely don't. At some they talk often on Slack public channels, and at others
nobody is talking on Slack. The difference isn't where their body is, the difference is cultural.
I'm arguing for remote, period. If you can find the right skills outside the US, please hire them! I have been at many orgs over the years where we struggled for months (sometimes years) to find halfway decent hires. Even with European and LATAM contractors, it wasn't much better; we'd go through 20-30 sub-standard contractors to find 1 or 2 with skill. And often they're better workers!
Yes, I am basically advocating for my salary to go down by hiring cheaper offshore workers. I am okay with that, as I know I'll get hired regardless (I am extremely skilled and will go toe-to-toe with any overseas hire). The amount of money we make, for the actual work we do, is crazy...
