There are several reasons, I think. Yes, I know I am not a "professional"... But I too struggled.

1. they can "afford" it. There is not struggle for real survival... so we can struggle with ourselves, our feelings...

2. the current MH model. Which is terribly enabling to unhealthy attitudes and behaviors. It marginalizes the power of human willpower and strenght.

3. yes, the big pharma. Pharmaceutical industry makes up for 10% of world's economy... and it has to run on something. Promoting biological model for something that cannot be measured... well, good business idea.

4. of course better accesibility of to MH services and awarness plays role here...

but tbh... if so many Americans have some issue that they (according to muchly touted medical model) they cannot control and that has control over their thoughts and actions... than they should hand over their superpower spector to some saner country. After all... lack of insight and all. Destructivness in behavior, impulsivness with money, bad relationships...
