Saving money is great but what does that do for the economy if no one is spending?

I think my generation gets an incredibly bad rap, most are not snowflake liberals as people want to believe when they bash millennials.
The Golden Generation (US) who lived through the depression and World War II are amazing in many ways, however, they and the Baby Boomers are the reason the world economy is so fucked.

These generations massively squandered resources and hoarded wealth by awarding themselves with unsustainable pensions and bonuses, allot of it on the taxpayer's dime. Besides bankrupting Social Security, Government workers in sectors like FBI have enriched themselves from jobs that were supposed to be public servants.
I feel you will just blame the government and bureaucracy for things like these but remember it was the older generations who voted, created a bloated federal system, misdirected our country, indebted the future generations, and raised and educated the terrible "millennials"
