As you say there is a major risk to your plan pension performance, There is also the risk long that pension performance getting surcharged
I suspect sometime in the future we will need to slow down non necessary consumption to stop the world from heating up,could happen sooner than you think
We see how trump tariffs effected our pension pot
may not be in the world best interest long term to allow stocks and shares to increase at the same rate as the have for the last 100 years,
The other thing can the world long term cope with people in collage to mid late twenties expecting to retire in there early fifties, again we could see action taken sooner than you think, labour or worker shortages may tilt tax policy, simple term
Socially necessary labor requirements to service early retirement will sooner or later drive policy decisions,
At present Goverment policy is to give tax relief and wait until retirement to get some of it back is a catch 22 situation
early retirement gets some tax back early but they are down labor output,
If you look around other web sites and Askaboutmoney you will already see resentment towards people who retired after spending 40 to 50 years in the work force which provided the services that gave them a better start in life the fear is this resentment will move to the early retirees,
