Defining Success?

So, there’s this picture of success we’re fed:
I graduate high school, go on to college, and earn one or more degrees in field(s) I’m relatively interested in. Upon graduating college, I move on to a career in those field(s) that I can work in until retirement, with a hefty retirement package waiting in my golden years.
Along the way, I met a partner, who is The One for me. We settle down and raise a functional family together, in a loving and supportive community.
We have a nice house, nice cars, nice kids, nice neighbors...

So vanilla it makes me want to puke, and it does not, at all, compare to the lives of struggling people that I see in myself, and around me...
why is it being promoted, then?
