The very rich are okay, poorer people get their rent paid and pension credit, people with small private pensions are no better off for having them
Yes it seems that saving what you can seems pointless when you can get pension credit anyway. Also paying off a mortgage just means you have to pay for old age care as they expect you to sell it to pay care home fees. If you don't own a house then care home fees are presumably covered by the state.
Luckily most people prefer to pay off and own their home & pay into a private pension. Otherwise we would all need pension credit
