To add, simply take a look at the % of USA federal spending that goes to Medicare and Social Security, which are benefits for the over 65 population. It's 1/3rd.

1/3rd of Americans are also over the age of 55, which will push that number higher.

We are consuming our young. As a 29 year old, unless technology advances radically and I have positions in the companies controlling it, I will not get what I put in.

There are many advanced economies in worse positions.

We can all blame whatever severely rich people exist, however the death by a thousand cuts brought on by too few supporting too many is the root of the issue.
