I'm sure there are no £60k households living on the poverty line, but you're certainly not going to get rich on this, especially if you live in the SE. Maybe if you're single living with your parents, yes. But a typically family of 4 will just be making ends meet on this salary. Of course they're going to be living in a bigger house than someone on half the salary, but it certainly wont be a beachside mansion or a big country pile. It'll most likely be a typical house on a typical housing estate.
You've got the top 1% of wage earners contributing to over a third of the tax bill, with the bottom 10% only contributing to 0.6% but consuming the vast majority. The squeezed middle contributing to almost two thirds of the tax bill. Not exactly a balanced and fair society.
If you're a family of 4 with a household income of £60k a year, you'll have a mortgage, child care costs that will be as much as your mortgage and nothing in return from the government. This doesn't leave a huge amount of disposable income out of the monthly salary - and its not going on a huge savings and investment portfolio. This doesn't feel like my definition of rich, not by monetary standards at least.
The squeezed middle don't want anything from the government, they would just like more of their own cash for themselves. And no-one should apologise to any spiteful, jealous socialist for that.
And we're not really the 7th richest nation in the world. Not when you bake into it our national debt to GDP ratio, which is worse than any of the PIGS nations. Its only our ability to keep on leveraging cheap debt that is keeping this country afloat. As soon as that is cut off or restricted then we're in for a collapse that will make Greece look like a minor crisis.
