Effective at what, political dominance? Eh..ressentiment and tearing down, attacking achievements of the strong and dominant while glorifying the weak and oppressed has actually worked extremely well.

Expressions of this sentiment like multiculturalism, mass migration and political correctness of the form of completely denouncing prior empires and dominant civilization is the status-quo order of the day. I think it is more uncertain how this type of worldview is opposed, not whether it is effective.
