If you are referring to the US, it's more because of the proportional treatment of indigenous, Hispanic, and black people by the government, historically speaking. Not because a particular group is too successful.
For example, if you read about the history of the Trail of Tears and slavery, those were long-term instances of oppression to specific groups. Not that Indians or East Asians haven't had periods of poor treatment, but the government had a hand in making it almost impossible for the aforementioned groups to accumulate wealth or property in America over the centuries.
If you look at the reason why Title IX exists, it is not because "men are too successful", if that makes sense.
