That’s a £29k salary.
In France it’s (the GBP equivalent) £17.6k, Netherlands £20k, Spain £12k, Italy nil. There must be a reason why this mix of socialist and centre right governments don’t set their at €33.7k
In Spain it's actually closer to 13k, which doesn't sound like a lot but cost of living is so much lower.
Average rent in London is apparently between 2 and 2.5k a month. In Madrid, it's less than half that. Monthly transport in Madrid is about 50 euros, which wouldn't even get you a month on London.
Then factor in things like eating out (breakfast with a coffee in Spain 2 or 3 euros, lunch with a beer 15 euros, a few beers and tapas 10/15 euros) and it's clearly easier to live comfortably in Spain on a low salary. Though Madrid would be a struggle on minimum wage.
Obviously, in both countries costs are lower outside the capital. In a small town here a little over a grand a month is more than sufficient to live a decent life. I'm not sure that's the case in the UK.
Anyway, I think the bigger issue is job security. If someone's getting 40 hours a week at £10.42, they're not doing too badly as long as they're in an area with affordable rent (not sure how many such areas exist). However, there are about a million people on zero hour contracts. Then there's the issue of sick pay.
