I’m sure I’ll give away my age on this.
Boomers were raised by the first consumer generation in America: the theory of consumerism to escape a permanent Great Depression. It went unquestioned that the value proposition for physical possessions might be so high that it verges on patriotic. Boomers are by far the biggest spenders.
But the important young people today are overseas. This is a statement about numbers and it’s a statement about young people in USA prioritizing sustainability. The value proposition to young Americans is reasonable for health care and nutrition/food stamps, and perhaps unreasonable for cable TV and corporate bailouts.
The original Green New Deal, the 2006 package of single-payer health care, job guarantees, free college paid by a carbon tax; that’s hard for me to call materialistic. Huge spending to offset the next generation’s collapsing consumerism.
