It's a chronic shame that the UK has not adopted this route of investing for the future. It could be investing in assets of the country. Owning say 40% of the utilities, highway and bridge tolls, national grid, power generation would have been a good start. Instead we squander short term income. Many public sector pensions are now funded this way.
I am a big believer in saving hard for your pension at the earliest opportunity. The state pension itself is a very basic back stop. The tapered tax relief on contributions needs to be looked at (the 60% tax band) together with the loss of tax relief for higher earners, and pension life time limits. The government made a good start insisting on work based pension schemes (was it the coalition that brought it in?) but it could do with another rethink.
