a single parent in London on £100K with a full childcare and housing bill is probably overdrawn each month. What happens on threads like this is that posters imagine that getting extra £xxx in gross income means you are immediately £xxx richer - but in reality, one starts paying tax, then loses subsidies such as 70% childcare, then tax credits and child benefit go, then the job becomes more demanding and extra expenses come with it. I have a three day business trip in mid-May that I HAVE to go to as a part of my job, it will cost almost half a grand in childcare for overnight / emergency cover. Not optional if I want to continue earning like I was, and quite common with jobs at £100K.
Poor you. Do you think a single parent on 25k in london somehow doesn’t have the same childcare, rent and other expenses that magically means they’re better off than you?
I earn 22k. Plus child benefit which takes me to 23.5k. I am not entitled to housing benefit, or tax credits. I can’t remember about childcare as my kids are teens now but it certainly wasn’t 70%.
But yes, your 150k job probably means you end up with less money/month 
I also am required to go to certain conferences and CPD events to progress or apply for promotion. It’s not solely restricted to high earners.
Sorry but I have no sympathy for those on this thread claiming they earn so much it makes them poor. Add to that childcare costs are relatively short term, once they hit secondary age you’ll still be earning 150k, and in your old age will have a pretty big pension.
Bet you wouldn’t swap your 150k for my 23.5k. Despite somehow seeming to think you have less disposable income.
