I don't think X culture can claim hard work and sacrifice as their own. Even so, I don't see how that defines the culture in a unique way to seperate it from other cultures. Hard work and sacrifice can be claimed by any civilization and has no need to be restricted by skin color or national identity.

I am all for advocating for hard work and sacrifice, but I am not sure how, whi or what white americains are being pushed out because of those beliefs.

Could you explain why you beleive this? Can you define what culture you mean by white americans?
