I feel you, OP.
In real terms, this increase represents an extra 9% of my mortgage or 2 days' travel costs.
I don't resent paying extra for things like funding the vaccine rollout, or paying furlough to key workers. I wouldn't even resent paying extra if it was redistributed to lower paid NHS workers.
I do resent paying extra to cover the idiotic Eat Out to Help Out schemes that were responsible for up to 17% of Covid infections over the summer and significantly contributed to the second wave. I do resent paying extra to cover furlough payments that should never have been claimed. Over 100,000 companies have repaid cash that they didn't need, but I can bet you a significantly higher number of companies haven't been publicly shamed and have no intentions of paying back the money that wasn't really aimed at them.
I think mainly I just resent our government.
There's an assumption that higher earners just swim around in cash, but I can assure you, it's all accounted for, and in my case, primarily goes to support other people. It's exhausting having so many financial dependents. If I stopped working, they'd all be screwed. Luckily, if I work myself into a grave, the death-in-service policy will take care of them all.
I knew the increase in tax would come eventually, and as much as I don't want to pay it, I know it's fairest that people who on paper are the higher earners should have to pay it. But my circumstances mean I'm not anywhere near as privileged as many posters will assume, and I'm just tired. OP, I sympathise with you, but I suspect very few on here will.
