They’re saying these people lived through a boom time, and had the easiest life of anyone as things have now gotten far worse to the point most people can’t even afford a home with a lifetime of work whereas their generation could outright own a house in a few years on a single income.
They coasted through life on easy mode, fucked the country for the current generation to keep their greedy lifestyle, didn’t save, and now have to be bailed out by society for a problem they made when were not even capable of supporting ourselves and now have to carry them as well.
