The article is about the US, so doesn’t mention the UK. But to quote the article “Loopholes benefiting the very wealthy should certainly be closed. The biggest problem in the American tax system is at the very top. The resetting of the basis for capital-gains tax upon death allows billionaires who hold on to assets, borrowing against them to fund spending, to avoid the levy entirely. The dodge is outrageous. Yet ending it would yield only a tiny amount of money, probably less than 0.1% of GDP annually. The same goes for raising inheritance tax, a good tax that has never generated much money.” I suspect the same in the UK.

The key point remains reasonable though - you can do all that but you just don’t raise enough money to meet people’s expectations

Find a political party you like, join it, start getting better people elected. Find an activist group (real, not online), wrestle with the compromises necessary to actually get anything done. Remember - a small group of dedicated people is the only thing that ever changes the world

The solution to lobbying and citizens united isn’t tax changes - it’s transparency in political funding and the electorate giving a fuck. And, pretty obviously, if most of a governments tax income came from a few hundred individuals they’d have enormous power, even if you did fix the lobbying/citizens united problem- they could just leave and crash your income overnight

Read the article. They’re in favour of closing loop holes and ensuring tax is progressive all the way to the top end (so taxing the mega rich properly) but point out the inconvenient (and true) truths that it won’t raise enough money to fix everything, and it concentrates political power in an even smaller number of people (those who are paying for everything) and encourages a culture of dependency in everyone else.
