I agree. Privilege definitely exist, but it's kind of a burned word. If you call someone privileged, you've made sure, that the person gets defensive and will not think about in any way.
I think it's more accurate to speak of resources. Everyone has some of them, but other people don't. Inherited money, having good relationships to your parents, having a stable upbringing, living in a good neighborhood and not being homeless, being perceived as competent, being physically or mentally healthy, are all valuable resources and everyone should try to see what resources they benefit from, where others can't. Sadly prejudice and racism/sexism/... exists, so your skin color is also a resource, making it easier to be perceived as trustworthy/competent/... which is a huge benefit.
No one did anything to deserve a growing up safely, being healthy, inheriting money, having white skin or even growing up in a certain nation. No one starts from zero, and it's just an obvious lie if you say otherwise. We as a society, should work on making these differences less relevant, when it comes to success and life satisfaction, wheather that's through public education, social benefits or reducing racism and prejudice.
