You have people born into money, celebrities, sports stars, and a lucky few entrepreneurs. Not many of the people who control a great deal of the wealth actually worked very hard to get it (not to say that there aren't some who do). The hardest working people don't make a lot of money.
Money isn't even a good indicator of your importance to society. A teacher is much more important than a baseball player, and certainly works harder for their money, yet makes a fraction of what the sports star makes.
Is a construction worker raising a family, less valuable than a young bachelor CFO?
There should never be a reason why someone dies of a preventable/curable ailment because they don't have the money.
There is a great deal more to life than money.
