Your luxury car repair drama is fleeting. Being wracked with stress about your entire life 24/7 only lets up when your mind finds a way to squirm out of it for a minute by watching a show or powering through a package of cookies on your couch.
Stress is not equivalent across all.
Mr BMW has no idea how much his energy bill was last month, smiles every time he pays his mortgage. Single mom carries a past due balance of $800 and barely makes rent each month. Two different, not equivalent, worlds.
In general, management level decisions can affect entire teams of workers and have downstream impacts on products used by millions of people. That is a form of pressure. So is the way pro athletes can be put on the spot, and it's not like their output has huge "real world" impact.
Yeah, obviously we'd all rather have pro athlete stress than single working mom stress. But there's 0 reason to strawman what that stress is.
This doesn't necessarily mean an equivalent high-stress life. The call center employee has fewer or worse options for dealing with stressors outside their job which they share with the executive.
> I need to eat.
> I need to travel.
> I need somewhere to live.
By and large these things cost money and the person who doesn't have to worry about having enough money for such things is going to have less stress in their life.
