Moving up or down in social class you may find yourself out of your element.
I grew up solidly middle class and took for granted health insurance and doctor visits whenever needed. When I got out on my own and didn't have such things I didn't know how to navigate the world. I lived for 4 years in a small town never seeing the doctor until an emergency situation forced me to go in - and then we were referred to the free medical clinic. Ha! I could have used that medical clinic for years if I had known such things existed. (Question 17 below)
Here's an interesting link (I can check off all the middle class boxes but practically none of the poverty or upper class items).http://www.asanet.org/sites/default/files/savvy/introtosociology/Documents/Hidden%20Rules%20of%20Social%20Class.htm
