I don’t believe this is true. There are plenty of roles that are happy to hire remotely. Sure, there is an in person requirement for many job listings but Ive found EMs/companies to be very flexible if they need to hire talent.

For people that can’t/dont want to move to the “hubs”, just know that there is absolutely still a career path. I will say though that you need to have above average communication skills and proactively build relationships during in person off-sites.
