These comments are so generalised.
Some pensioners are living in the lap of luxury, some pensioners are struggling to get by, some help their families, some help charities, some go on cruises, some go to bingo, etc., etc. It's ridiculous to lump everybody together.
Speaking for ourselves, we are better off now than when working because we have paid for our house and we both have pretty good pensions. However, we have given substantial support to our children financially, providing house deposits, holidays, etc. etc., and providing childcare. Additionally, I do a few hours volunteering and we donate on a regular basis to various charities. I believe we are fairly representative of quite a lot of pensioners.
As others have said on GN previously, it's yet another example of setting one group of people off against another - "divide and rule".
