Ending the triple lock doesn't mean:
- reducing the state pension (it means it will rise, just not as fast)
- taking away someone's entitlement to a fast-rising pension (nobody was promised a triple lock during their working age, at least not until 2011)
Ending the state pension as a concept does not mean:
- taking away people's pensions today (people would continue to get their pension for the rest of their lives, since they "paid into the system")
- taking away pensions from people who've already paid NI for many years (they would be given the option to continue paying NI and get state pension as if nothing changed, or trade part of their pension for a private fund instead)
What we COULD do when abolishing the state pension is giving young people today a tax break (e.g. no NI) in exchange for not promising them any state pension ever. Instead, a mandatory private pension insurance fee would be introduced, forcing employees to pay a percentage of their salary into a pension fund that is privately managed. In the long run, this means that people will get much more money when they retire compared to people who "paid into" the state pension. And the savings for the state (30-40 years down the line) would be immense.
