Certainly not.
We cannot base someone's attitude based on his physical appearance.
Some educated men can act more uneducated than those who have not stepped on a school; and some uneducated men can act more educated than those who have the highest degree.
Poor people can sometimes be more philanthropic than the wealthy; and rich people can sometimes be more greedy than the poor.
The wealth you possess or don't, the house you live in, the clothes you wear, the quantity of friends you keep does not define your character. With this said, even if you are the most broke, you wear the most tattered clothes or if you live in the slums, you can be a good person and can make a difference in other's lives. On the other hand, even if you live in the biggest and most comfortable house, you drive the most luxurious car or possess all the wealth the world can offer, you can be the most evil person.
