Is affordable housing not subsidised by someone else who has had to pay full price for theirs, should my children who have huge mortgages pay tax so someone else can get an equal house subsidised not sure that is fair.
Should I be made to feel like a pariah because I have a holiday home (I don't actually, but if I did) it's not my fault the government have let in millions of people without the infrastructure and housing for them.
Only in the same way that all social measures (education, health, benefits etc) are subsidised by those who don't need them so that those who do (which might one day include them) can have access to them when needed.
A worker subsidises those who don't work, but one day might need to claim benefits. Someone who is healthy subsidises people in hospital, but might take ill one day, and so on.
Social housing used to be a safety net - in fact that's overstating it, it used to be an option for all who wanted it - but since it was sold off it has become a scarce resource.
Holiday homes are a different case, IMO - as they tend to be centred around particular areas they rip the heart out of the communities that used to thrive in those places. With few people there in the winter, and those who are tending to bring food with them and not using services such as GP surgeries, bus routes, libraries and so on, shops and services close, so residents move out and the cycle continues.
