That being said, there are plenty of toxic work environments out there and highly competitive, cut-throat offices often create an "every man for himself" mindset. Shout out to anyone who has every worked in a restaurant, taken a weekend off and shown up to a new person in their position and their name mysteriously "removed from the schedule." Americans especially have a "you can't relax unless you worked hard enough to deserve it, 9-9" approach to their careers, and it can be incredibly unhealthy.
Especially in the gig economy, it's not unusual for people to work multiple jobs, often having an office job as well as a side-gig at night or on weekends. Judging your co-workers for how they choose to manage their finances or pay for the lifestyle they desire is rude and none of your business, however things can definitely get awkward at the salad bar when someone disagrees.
