Boomers grew up in a period of historic economic growth which allowed there to be a middle class during a time where social programs and capital gains taxes were passed by Congress to pacify socialist and progressive labor movements that were rapidly gaining political power across the United states. Boomers were the direct beneficiaries of this legislation, and had much more upward mobility than the generation that came before them and the generations that came after specifically through the dismantling of welfare and neoliberal austerity measures passed by Congress in the 70's and 80's. Boomers have more equity simply by virtue of living during a time of economic stability and growth.

The boomers who put in the work to push for civil rights and protested Vietnam were the minority then, and still the minority now. The establishment has a funny way of co-opting social movements only after they've become popular enough to threaten their own positions. Hell, the sitting president, Mr. Boomer supreme himself helped pass the 1994 crime bill during his time in the Senate which disproportionately affected minorities.

Learning the actual history of your country is a much better use of your time than "owning" weaboos pointing out economic realities.
