Well quite. People keep taking about OP's enormous mortgage giving her an amazing lifestyle house but £2500 mortgage repayments is 25 year repayment on a £400k mortgage.
£500k (assuming she has £100k equity) buys a 1 bed flat in Islington. Or a small house in a very ordinary part of zone 4.
I'm assuming she has significantly more equity, built up during their pre-DC years. Hence not having saved up for childcare.
Not sure whether this is a real thread, but the points being brought up are very real. 2 professional-salary parents working in London get totally screwed over by taxes and high housing, childcare and commuting costs. It does make you wonder whether it's worth it.
But the economy is totally screwed if the part of the tax-base who pay for most of the country's costs decide to work less for a more relaxed life in a cheaper part of the country.
The top 10% of taxpayers paid 60% of all income tax last year, and the top 1% paid 30% of income tax.
Now admittedly some of that top 1% is going to be skewed by the crazy wealthy. But given that top 10% salary is £67k and top 2% salary is £100k, it's taxpayers in the OP's category (approx £80k each, in a couple with both parents working full time in professional jobs) who are paying 30% of the country's running costs (schools, hospitals, benefits, pensions etc). And who could move to a more relaxed job in an area of the country with low housing costs with no real reduction in disposable income after housing, a big improvement in time spent with kids, and the main difference being a much lower tax bill. The main downside is not having paid off an expensive house as an asset on retirement. But if your kids remain in the SE for work, you probably wouldn't want to cash in your equity at retirement anyway: you need to live somewhere, and won't want to move 200 miles away from your kids and possible grandkids. So that asset isn't doing you much good.
I agree OP that it's all a bit shit.
