Lol, imagine to work your ass off until 67 and get to enjoy the last 7-8 years of your life, IF you're lucky and none of the usual killers finish you off before then (let's say lifestyle-related, genetically-inherited, cancerous or just plain-bad-luck illnesses).
What do you have energy for, even? Life quality is usually poor at that age, for the vast majority. What have you worked for, for let's say 40+ years, earned the right just to pay bills, eat and have basic medical care?
I know the solution is to invest in your own retirement fund (or stock market etc.) and retire early, but how many of us have the privilege of having enough free cash each month to do that? 20-30 years is a long period of time, banks come and go, inflation may eat it all up, who knows...
And I also know the state is the state, politics are politics, economy is the economy, but I would say right around 50-55 is the proper (humane) cutoff time, especially for 9-5 (or physically demanding jobs). At that time people usually are fed up with working (without any purpose) - I notice it all the time. Just let everyone enjoy the fruits of their labours and live the last 20 years of their life enjoying what is left of it.
