Just where is the line between poor and rich?

When does poorness start? A person who was dirt poor come into money around $50,000 to $78,000 they would believe they were doing quite well. Another person who lived very affluent had beach houses, sprawling mansions, $1,500 handbags, $120 sun shades, $750 dollar boots, $80,000 or or vehicles if they lost it all and only had $50,000 left they would think they were broke. Is there really a point or level where you can draw the line, this side you are poor, on this side you are rich? What of those who have hardly a cent to their name but they are happy and content just making it day to day without any of the extras? Isn’t being poor or rich more a state of being or in the mind than the bank account?
