There is already a problem in the UK with a lot of people not saving enough for their retirement and the government has taken steps such as introducing auto enrolment into company pension schemes to push people to improve their private pension provision. Introducing means testing of the state pension will only make that situation worse. Why save for your retirement if the government is going to punish you by taking away your state pension? Also financial expectations have been set, particularly for those that have already built up an entitlement to the state pension, but may still be many years away from claiming it.
There's a whole other debate about the impact of AI/technology on jobs and the long term need to move to a Universal Basic Income. But sticking to pensions I really can't see a UK government introducing means testing, unless they completely take leave of their senses. Or at least set it at such a high level that it only impacts on the genuinely rich, rather than working class people who have been prudent in planning for their retirement.
Steps that seem more likely:
- Weakening the triple lock
- Further increases in the state pension age
- Increasing the amount of qualifying years needed (it previously changed from 30 to 35 years and I can imagine a future change to 40 years contributions being required for a full state pension)
- Additional taxation to claw back more money from better off pensioners
