When confronted with a convenience store, where you can buy food, a washing machine to wash your cloths, or even Bill Gates that wants to donate 99% of his money upon his death to philanthropy, does it strike you as important that the value of one's utility is important to consider outside of economics and instead to the ethical realm of thought?

With that said, it's my opinion that the value of utility (a unit of money) has become so wide and thriving that people living nowadays equate the amount of money a person has with the concept of how much success or happiness you have obtained. The success of economics has led to longer lifespans, greater satisfaction, and prosperity. Issues raised by economists about inequality and exploitation of the masses along with alienation of the consumer, are pertinent; but mostly seem like a byproduct of the machinery of capitalism. But capitalism is about wealth, not ethics, so let us not conflate the two. Socialism is, to some, a response to unfettered capitalism. Now, I don't want to talk about the merits of capitalism over socialism or vice-versa as my main concern here is that of why utility arose to such a degree of importance in our everyday lives and yet is still treated so poorly by philosophers.

I don't want to explain why utility is important or why it shouldn't be neglected; but, would rather focus the thread on why philosophers neglect the import of utility to ethics, while meanwhile the people in the world that have the most amount of money seem to be outright philanthropists with donating 90-99 percent of their wealth to philanthropic causes.
