The author is lamenting the passing of an era. White males dominating, with other races subservient, women unable to get credit or livable jobs, gays having to stay in the closet, and the police willing and eager to enforce the status quo.

He's right, it's gone, with the freedoms and liberties now available to minorities coming at the expense of white males. The shift is a problem only to people who think of themselves as a white male and expect power and authority to accrue to them because of that. Others, more secure, find it easy to recognize minorities as equals because it doesn't cost them anything.

Hopefully, the US the author mourns is gone, and hopefully the author quickly moves into the new world, accepting the rights of others, living lives as preached by Jesus Christ. If they will only read the New Testament they will see that Jesus preached inclusion, acceptance, freedom for all. Except as a child, one time, he criticized the "money-changers". One doesn't need to pray to understand what he would have thought of the bankers who give themselves huge "bonuses" even though their companies lose money.
And yet that's the hallmark of the world that author sadly watches pass from existence. It's natural, it's normal. And they don't believe in evolution!!!
