What happens to stock market when everyone is given 100k to invest? The inflation adjustment is likely understated as you’re basing on historical factors and this is large macro shock to the system that needs to be adjusted for as well.

I also still don’t think this helps most people during the bulk of their lives. Most people in this cohort don’t save now, having knowledge of a more secure retirement wouldn’t change much for them. It’s not like they can turn off 401k contributions and have extra pocket money today.
