What alternative are you offering? Not taxing anyone much leaves us with a society that simply doesn't function, we see that right now. FUD about "well, they could tax the wrong people" is pretty irrelevant when we are already in a situation where most people are facing poverty and ruin. If this is all we can expect, then might as well roll the dice on doing it right.
Of course, the idea there is no way to actually tax the rich is absurd, we can do it, we have just had decades of government with no will to do so.
This is not FUD. They always tax the wrong people. We as a society can do many, many things but we simply cant coordinate to do them. And indeed we should consider this lack of coordination (for a lack of a better term) as something we should take into account when making decisions.
I honestly dont have a solution to this problem.
"We voted in the Tories again and they continued to lower taxes for their mates and screw over the poor" is hardly trying everything. Throwing your hands in the air, accepting suffering and society collapsing while they profit off it isn't an answer.
You are saying you don't think it's impossible, just that no one is willing to do it: we have to create pressure to do the right thing, and demand it, not make excuses and accept it as inevitable.
Which way is that, other than the ways we already do it?
- Tax capital gains and dividends that are classically the rates actually paid by the megarich rather than income tax.
- Tax wealth directly rather than just income.
- Tax much more heavily generally and commit to a significant basic income to ensure everyone has a solid baseline.
This is just off the top of my head, we have an entire government of people and a huge field of existing research and ideas, not to mention other countries and historic data on taxing more than the UK right now to look at.
