A lot of the old world money is humble. It has worked hard for it. It is generous, large hearted.
A lot of the new money is arrogant, with a massive sense of entitlement. Its got it a little easier than it ever imagined, and needs to put on a display of inflated self worth. Its also more money minded and usually not big hearted. Its more suspicious of motives, others and believes in exclusivity and existing in islands.
