There's also this (Guardian narrative, not a quote from anyone)
At the same time most people are faced with stagnating wages
Real earnings have been growing continuously for 2 years. Some of that was making up for the post-Covid squeeze, but the recovery has been pretty decent. Why make it sound worse than it is? The only people who gain from this are people offering simple solutions.
This bit seems to be about income, not wealth at all.
The campaign aims to highlight the growth in extreme wealth held by individuals and corporations in the UK. It calls on the government to introduce a 2% tax on assets over £10m, shut down tax loopholes and increase the tax paid on property and shares so that capital gains tax is equal to income tax. It is also urging the government to stop using public money to bail out big polluters such as failing water companies and fossil fuel firms
Which tax loopholes do they mean? Nobody ever says, but some (particularly on inheritance) were closed in the Budget, for all the credit the Government get. "Tax loophole" often means someone not understanding that tax isn't paid on turnover.
What water companies and fossil fuel firms have been bailed out? Bulb was bailed out, if that's what they mean, but the Government made a profit on it.
Capital Gains Tax could only be equalized to income tax if it didn't have an inflation allowance, which would be incredibly harsh. CGT could go higher, but again, it did go up in the Budget. And everywhere has lower rates for CGT, it's not just a UK thing.
