The US isn't wealthy in any easily calculatable sense. They have been borrowing from it's grandchildren for a long time now. Most other western countries are doing the same. Some of those countries though have forced retirement savings but otherwise it's all borrowed money.
Blaming any specific generation for the framework the previous one set up for them is just flat out ignoring what it means to be a human being living in a society.
