Probably because your wife wasn't there in the trenches like you were. You created the wealth, she just benefitted from it.
Please note that I'm not ragging on women. Children of rich families would also probably have the same attitude, regardless of gender.
Honestly, I'm surprised that there aren't a few therapists who work exclusively with founders - I'd honestly love to see a VC firm with a therapist on staff for its founders.
It seems like it couldn't possibly produce a dynamic that's much different than say corporate HR. Wherein the helping hand extended to the employee is always beneath that of the one that's protecting the company.
But, maybe that's just me exposing my rank cynicism, which by some measures is a personality flaw in its own right.
Maybe better if they could just refer some independent therapists who have experience with founders.
