You ARE better off.
But you are also in the top 20%.
The bottom 80% are not as lucky as you. The bottom 80% cannot afford 2 cars, or a house, or cable, or an iPhone, etc.
Have some fucking perspective. You are doing well; but look around you. The rest of the country is NOT.
A tremendous part of the economy is out of work and cannot even afford to go to the doctor. You're living in a bubble.
