I'm open mouthed at the idea that "most" SAHMs "could" earn £38k themselves. Surely it's more realistic to say that "some" could.
Many SAHMs, whether they're capable of earning anything - £10k, £38k or more - are currently SAHM because ..... errrr .... there are hardly any jobs around. So to suggest that had they put themselves out a bit in the past "most" SAHMs could be earning £38k (or more I presume) is naiive ..... unless I'm looking in all the wrong places I certainly haven't noticed a plethora of vacancies offering at least £38k.
It also misses the point that many many individuals earning a LOT less than £38k have also struggled - and continue to struggle - with difficult, tiring, stressful training and employment, and childcare, and are still unable to earn anywhere near that figure despite the fact they're doing useful worthwhile jobs. After all, £38k is significantly higher than the so called average wage. So to suggest that SAHM who've "chosen" to forego that mythical £38k have, in effect, no-one but themselves to blame is just ridiculous.
I'm also not so sure a 2 adult household with 1 SAHM and 1 £60k is broadly speaking as well off as 2 adults both working with combined £98k. That's a very sweeping statement and takes no account of no of kids, or amount of childcare needed, or proximity to work. It's quite possible for example that the £98k household gets free childcare from family, or that kids are 12 plus and parents are happy to have them at home on their own, and that parents work from home or very close by meaning their expenditure is significantly reduced. But of course I accept that to hand out CB - or not - on the basis of means testing such as housing expenses, childcare, commuting costs and so on would be impossible to administer ..... but that's why, IMO, it's unfair to retain CB for combined household income where individuals earn less than £50k each but where it might, feasibly, add up to a lot more than £60k, as people's individual circumstances do vary so hugely.
And I go back to the issue of financial abuse. Just because your dad earns £60k or more doesn't automatically mean kids get everything they need. They should of course but we all know not all families are perfect. Just how difficult is it going to be for women in that situation to continue claiming CB for NI purposes if they fear their husband's reaction when invariably it's going to get clawed back out of "his" money ? How many women like that are going to be told they'll have to "eke out" what (probably paltry) housekeeping they're "allowed" because he doesn't see why he should lose out ?
