Is Utilitarianism a thing?

I stumbled across this video this afternoon, and it got me thinking….

I’ve always found all normative ethical foundations to be lacking, from virtue ethics to deontology and consequentialism, each for its own reasons. Utilitarianism falls under consequentialism and is the foundation of much economic theory, the concept that people maximise this notion of pleasure. Aside from the other issues in utility theory, pleasure is not measurable.

But if emotions are also the result of social construction, what would be optimised if we could even maximise in the first place?

Emotions are not what we think they are.
