I think in part, some think the word triple means a trebling of the state pension, or three times what everybody else is getting. Whereas in reality it just means there are three things that are looked at.
In reality a small percentage of not a huge figure is not a lot. If average wages rise by 3%, and that is the top figure of the three figures in the 'triple lock' used to increase the state pension, 3% of £12k (using rounded figures for ease) is less than 3% of average wage (for example £30,000). So the pension falls behind.
Possible options, maybe,
1. Go to a double lock - will this make much difference?
2. Go to a single lock - ditto 1 above.
3. Freeze pensions - hardly a winner and many pensioners will struggle perhaps.
4. A flat rate increase eg state pension goes up £800pa MP's pay goes up £800pa etc. Everyone gets an increase, but £800 will mean more to someone on £12k than to someone on £100k
5. Perhaps get today's 18 year olds (and all future young people)to not pay as much tax, perhaps 2% less than basic rate, they dont get a pension but they can use the 2% money they aren't paying as tax to save/fund their own retirement and they could have options on how to do this, but they wont get a state pension.
[The above may be shredded as ridiculous, but just Sunday morning thoughts - as I have found this thread interesting in several ways)
