I can think of lots of debts that boomers incurred that will need to be paid (or absorbed) by subsequent generations.

- A vietnam war whose costs changed our economy and lead to the end of the dollars convertibility.

- A transition to urban life without investment in public transportation leading to a half century of malinvestment and disjointed transport infrastructure.

- Failure to invest the time and thought into learning how to eat and walk when you don't live on the farm anymore. Three square meals a day combined with driving everywhere has lead to an obesity and diabetic crisis.
