In truth, NIMBYism is a gigantic problem even (especially!) in places where people profess to hold liberal and/or progressive values. It's a massive contributor to the housing crisis in California, for instance... and the attitude is not limited to Boomers, who are reaching the age now where they're as likely to be entering assisted living homes as they are to be stubbornly holding on to a house in the 'burbs that's appreciated 1000% since they bought it. GenX and even those us Millennials who are fortunate enough to own can be and often are just as guilty of NIMBYism as the old folks.
