That's true. So in order to get more accurate numbers (since the rules are quite complicated) I put the numbers into www.entitledto.co.uk
I've put 2 NMW adults with 2 preschoolers in full time nursery (£1895 each per month - pretty normal for the SE) and renting a 2-bed home in outer SW London (£344/week allowed for a 2-bed in that area), and they get £703 in benefits per week. Add the 2xNMW jobs at £19.5k net, and their net annual income is £75,500. Hmm...
If we have a single NMW worker, UC goes up to £863 per week. So net annual income is £64,376.
The single £101,000k worker pays £32k of tax, to end up with a net salary of £69k. And gets zilch from the government, because they 'earn so much'.
That's unbelievably only £4.5k more net income per year than the NMW single parent with the same children and costs. Despite earning £80k more - almost 5 times as much.
But that's without counting the student debt (which you almost certainly need to get a job at that level). £6.5k per year in student debt repayments from the high earner. Nothing from the NMW earner.
So actually, if both have been to university, a single parent of 2 preschoolers is better off on NMW than on £101k per year.
"childcare and flexible working is prohibitive in a system designed for the wealthy"
How, exactly? What a fucking joke.
