We have a slight issue with 'identity' in the US. I need to read more Tocqueville before I really start espousing any diagnostic on the psyche of the US but...
This type of mindset is what occurs when someone searches for their identity and meaning then places that whole 'life's worth' in the form of businesses or enterprising endeavors.
It can be broadly characterized as externalizing one's identity, which is painfully likely to fail or let you down in some way. In its most extreme forms, it's really a mental disorder (bordering the wildly high-functioning creative schizophrenic) that the Startup Zeitgeist has hailed as 'how to innovate' and find your 'life's work.' The disorders become evident once one sacrifices all of self at the alter of this 'give a shit' goal - burn out is not the goal of human life.
I'll say I'm recovering from this mindset and have a fonder appreciation for what it means to foster a community (be that business, HOA, religious group, friend group, etc) that allows you to have a 'life's work' that gives you resources to flourish in ways you never thought you could.
