Most families are on less than this and get by fine. My household is on under 20k in total, and we get by tolerably but without luxury. Nobody needs a whole lot more than 70k anyway, though I'm not sure how much a place like London would diminish it via increased living and accommodation costs.
We eat and consume fairly ethically, and I've had plenty of opportunities, but often the wider family has to help out, and I wouldn't use my tolerable lifestyle as justification for any country keeping its citizens on such a low income. 70k is a far more reasonable value, and I'm sure it's actually significantly higher than necessary. In a better regulated and fairer housing market, predatory landlords and ridiculously large mortgages wouldn't take up huge percentages of everybody's income, and we could get by with total comfort on currently very average wages.

It’s a great salary for relatively early in a career and absolutely enough to support a family in a comfortable if not extravagant way. Many couples have dual incomes below this and get by. The only proviso might be property prices, if you live in an exorbitant area and want to buy a reasonable home. Weigh up how much you need to save and spend to get the accommodation you want. If you have the prospect of further career development and additional income from a partner you are in a very good position.
