Will retirement be impossible for most millennials?

1) What kind of claim is this?

This is a broad future-outcome claim with stated causes.

2) What context is assumed or missing?

Definitions of retirement, location, and time horizon are not stated.

3) What has to be true for this to work?

Wages would need to lag costs long term and saving routes would remain blocked.

4) When would this not hold?

The claim weakens if earnings, policy, or asset access changes over time.

5) What follows if we accept it?

The future may be framed as structurally closed for a whole group.
