The whole 'second home' issue is part of the property ownership fetish that we have in this country. In other countries is is more normal for young people and families to rent their homes, and this does allow for a much easier system of work and living mobility. Of course, rental properties are at best owned by the state, not private landlords and need to have extremely stringent laws regarding the right of those renting.
When I was a child, the biggest ambition of people I knew was to get a Council property (flat or house). To get away from private landlords. People loved their Council properties and when my parents obtained a house on an new built estate in Essex, they were in seven heaven. Those there had little money, but they worked so hard turning those houses and gardens into things of beauty.
When I married in the early sixties, no chance of a council flat for newly weds like us - to prevent going into slum landlord properties we had to try to buy (or rather pay the mortgage companies).
So, I became the first person in my family to do this. The 'Property Owning' democracy it was called. Don't know about others but led to so many years of being very, very hard-up.
Yes, I know - it has worked out in my favour in the long run - but had we all been able to live in appropriate Council properties it could have been so much better. Yet, all my children have had to go along the road of purchasing their own mortgages, etc.
None, would ever have a second home. They will live with owning their own home, but never owning someone else's or, of owning a property and only living in it for weekends and holidays, whilst preventing locals living there.
We each of us, have our own 'moral codes', and this is one that I know none in my family could break
