Of course they can rise, but the richest corporations and individuals buy the best tax advice known to man.Not necessarily - taxes can rise for corporations and the wealthy. Trickle down economics has been been shown to be an abject failure (or a sham) over the past 40 years.
...and do you know what? The UK is awash with accountants only too willing to sell the best loopholes for a bit of lining their own pockets.
If we all wanted to, we could hit the likes of Amazon hard in the pocket, by not buying from them until they cave and pay more tax.
But we don't do we. It's all far too convenient.
I'm resigned to the fact that the richest can just shovel their money around to the next tax haven on the list.
