No tax and benefit system is perfect. There’s always a balancing of ensuring benefits are well targeted (to those who need them) against ensuring good levels of take-up and low admin costs and preventing fraud.
The current system ensures families with no earner above £50k qualify. That’s the main aim. For them, it’s easy to qualify and apply and for the government crucially it’s cheap to administer which is vital as it’s a low level benefit anyway, so high admin costs can negate the benefits of it.
Yes, those with one earner on £62k won’t qualify for anything, whilst a household on £99k split evenly probably will. But the giv knows the £60k household have £60k and so their ‘need’ isn’t that great. They might feel it’s unfair, but need is the key issue and the current policy ensures households with less than £60k will definitely get some. Purpose achieved.
Yes, it would be good if they could save the expenditure going to households with £60k to £99k. It would mean there was more cash to spend on those that need it. But the cost of administering it would probably exceed the amount of cash given in these benefits. That has to be considered. It’s the key reason it’s as it is. The government always has to accept it will spend some money on benefits to those who don’t really need them, and that the ‘cost’ of that is worth it because it means a cheap admin method can be used and ultimately and overall the gain and net benefit exceeds the costs. It’s about the bigger picture, not individuals who might be getting a benefit they might not need.
Who doesn’t like the current policy? Is it those on low incomes who are suffering poverty? No. Because those people receive it. Who doesn’t like it? It’s those with a high earner (over £60k) who doesn’t like to think of other families who have more cash than them (2 earner households) getting it. Does the government care that they feel a bit disgruntled? No, the purpose of the benefit isn’t to even up incomes of the affluent, but the provision of the benefit to those under £60k. Is it achieving that? Yes, Job done. People feeling a bit out -out - unfortunate side effect, but nothing the governments concerned about.
