Yes, this is probably the biggest factor, but the fact of the matter is that large numbers of people have to live in places where houses are expensive. To penalise those people further is stupid.
Yes, although there are points that follow on from this to consider. On any reasonable basis, private healthcare is not an extravagance when state healthcare is in a state of failure. Yes, it’s an advantage, but it’s not either wrong or excessive to do what you can with your family’s healthcare or education. To the extent that private education confers an unfair advantage, that must mean that its outcomes are better than state education (whether that is true any more is very debatable) and therefore that the stock of the nation’s labour force is more highly-skilled than it otherwise would be. Penalising that is crazy as well as counterproductive.
It depends if you’re working 40 hours a week with no real pressure, or 100 hours a week with everything at stake. If it’s the former, one wonders whether the Scots, indefensibly chippy already, are really ready for 50 million English campers every summer. There’s nothing wrong with a two week holiday in France.
Unless you’re taking a silly attitude to this, it doesn’t really matter. The key thing I suppose is that someone needs to be able to buy the two or three million new cars the nation needs each year. I think anything short of e.g. Bentleys, Ferraris, helicopters is reasonable.
Grouse shooting might be a bit much, but the plebs’ sport ought to provide a guide as to the absolute minimum you couldn’t defend penalising. A football season ticket is around £800 per head. Family of four: £5500 of salary before tax. That’s one (“working class”) activity.
As I asked…what’s yours? My definition was certainly subjective, but not dangerously so. I really don’t think that it included anything remotely unreasonable.
