One of the biggest problems in these circumstances is that averages are pretty meaningless. 50k income in one part of the country is very different to 50k in another in terms of what you get for it. House prices are the obvious, but even council tax can be as much as £1k a year different at middle levels, more at higher levels.
The Covid effects are already being felt unequally, there are likely to be more job losses in lower earning jobs (so far) but there is also likely to be more furlough. Those in higher earning jobs are more likely to have had to continue working whilst also taking on extra responsibilities like homeschooling. We are also seeing significant pay cuts in some sectors as companies try to stay afloat, many at higher pay levels and there’s only a certain extent to which outgoings can be adjusted to accommodate this. Those who worked hard throughout, keeping the economy ticking over, have already been asked to pay in other ways for people on furlough and grants to self employed. I personally don’t think it’s unreasonable to ask those who benefited from furlough to contribute to paying for it in some way. Yes we all benefited to some extent but you can understand why the family who is homeschooling, working two FT jobs and has taken a pay cut all whilst their neighbour has a few months off work already feels like the costs are unequally distributed. Most (like us) will see it as doing their bit, but the costs of recovery should be shared to a manageable level and not just passed on to people we think have more than us.
The areas that need to be changed are loopholes of course and also some of the structural factors. Self employment rates need to be brought in line with PAYE, the triple lock on state pensions should be reviewed (personally I think they should be means tested but that’s another story!) and CGT should be increased to same level as income tax. Likewise, we need to find a way of accessing some of the huge amounts of untaxed wealth accumulated in property over the past 30 years, much of which is disproportionately owned by retirees who draw significantly less taxable income and actually underspend relative to their wealth position than working age groups (again averages distort reality in this group but overall that’s the picture).
Overall my point is that everyone needs to contribute to recovery, including those who benefited and those who have broader shoulders, but in addition we need to find better ways than income tax to offset costs. Oh, and don’t forget the inflation we will all need to factor in to prices over the next few years as businesses try to recoup their losses from us too. It will be a double whammy of higher taxes and higher prices all around. But hopefully flexible working is here to stay at least?? I think many people would gladly pay a bit more to have a lifestyle benefit (and travel / lunch etc) savings) like that!
