Totally disagree. Many people have moved to the cities for work, or their families did, and they would like a little bit of quality of life by spending their hard earned cash on a home they can enjoy and might retire to. It would be better still if there hadn't been the Highland Clearances, or the government actually stimulated the economy so that jobs weren't concentrated in a few areas, but considering they pay extra stamp duty and council and income tax on the money they use to buy said holiday home, YABU.
But all you end up with in preventing holiday homes is British people taking their cash elsewhere and buying a holiday home abroad, where they aren't necessarily penalised by stamp duty and council tax. Which to me, is crazy.
And remember, in oh-so-socialist Scandinavia and Russia, having a holiday home is normal and achievable for most people. And they aren't all tiny cabins in the woods.
Personally, I'd be quite happy with a tiny cabin as a holiday home, but the UK planning laws won't allow them, or if they are, they have to be on all year round camping sites with massive fees, since building plots in this country are so massively expensive.
I have a small house in Scotland which I've been trying to sell for 2 years, and can't, because the Scottish Government's taxes and failing economy have decimated the market, along with building vast swathes of new housing estates everywhere. It was never intended to be a holiday home, it was bought because I moved there for work - a mistake I will never make again!
