You seem to think that people on high incomes shouldn't receive state support
I've said no such thing, you are projecting.
Meanwhile, you have no idea of the OP's situation, and outgoings, so it's impossible to make judgmental comparisons to your own or other's lives
Oh come on. Seriously - anybody struggling on 100k a year needs to get a grip on money management. Its bloody insulting to the vast majority struggling along on average earnings.
The OP started off by saying she had no disposable income, then changed that to a definition of "no disposable" which excluded savings and other costs. No disposable income means nothing beyond bare essentials - it means no income to put into savings.
The point I made up thread, is that the situation described (ie career points where you work more for less benefit) are the norm and nothing to do with sex or the existence of children.
There are many issues women face in the workplace which men don't but anomalies around top rates of tax are not one of them. Every major career step has a period of time where you work more for less to get the next rung on the ladder. This is not only true for high paid careers - talk to anyone in public sector or service jobs and they will tell of the time they spent doing the level above's job for free before getting that promotion.
The choice is really simple - do you want the promotion more than you want family life at this time? If yes then go for it, if not then defer it. Any of us in this type of path have to make those decisions - male or female.
You can’t post anything on mumsnet related to money without getting told how lucky you are etc
Well if you want to talk about life being tough and having no disposable income on 100K then you can expect to be challenged because its nonsense.
And since I'm well above that you can safely assume I'm not suffering from envy. What I do have a realistic view of what it takes to get to that level and the fact that it isn't just a smooth upward trajectory for anyone. Every career path has ups and downs and some of the downs are working more for less when you want promotion.
