I don't think it's just 'old men' @Wildo My 58 y.o. cousin has rented (social housing) for 30 years, and now lives in a neat little bungalow with her DH, costing £380 a month rent. Around 2 years ago, she was lectured by the gas man (who was doing a routine safety check,) and he was only about 38!
He told her that she and her husband (who was at work at the time,) was 'stupid' for renting, and 'buying is the way to go.' Why pay someone else's mortgage he asked. (It's council so no-one's mortgage is being paid.) 🙄 Also, property is an investment, she will have nothing to leave her kids, she has no security, it's character building buying a house, it's what 'grown-ups' do. 
I would have told him to back off and stay out of my business because he knows sod-all about my life, but she is timid and just sat there listening. However, she was still thinking 'well we have one child only who is loaded and has a 5 bed detached house, so doesn't need our little bungalow worth £110K, and also we may need to go into care and the house would be sold for that anyway, and also the rent will be paid if me and my husband are ever long term sick or unemployed, and also we never have to pay for any repairs or maintenance. New heating system, new boiler, new roof, new electrics, new kitchen, new bathroom, new windows and doors, new fence etc etc etc.... all covered. And total security as it's a tenancy for life.
As he blathered on, he said his wife had received a £90,000 inheritance 2 years before, that they had used as a deposit on their £145,000 3 bed semi. Yeah very 'character-building' and 'grown up' buying a house when two thirds of the house value is given to you!
Absolute twat.
