How about just taxing the rich? The rich benefit from everyone's education.
Several reasons.
Despite the rich being richer than ever, there simply aren't enough of them to generate sufficient tax income. This is why taxation tends to fall on the middle classes because there are far more of them. It's the same reason that even though executive pay grabs headlines (and in many cases IMO is far too high), chopping the chief executive's pay by 80% makes much less of a difference to the bottom line than restricting pay increases for the workforce as a whole by a fraction of a percent.
The rich are very, very good at avoiding paying tax. This is not to say that we shouldn't try to collect unpaid taxes or close tax loopholes but the truth is that even someone like myself who is comfortably off rather than rich and who is a business owner has far greater scope for (perfectly legal) tax avoidance than someone with fewer resources. Heck, I can afford to put money into tax-exempt savings vehicles whereas someone without any spare income cannot.
There comes a point in time where costs of attempting to collect tax exceed the money that's going to be brought in. According to Private Eye (but contrary to HMRC) we may have already reached this point.
Also, it doesn't appear that Corbyn thinks too much of the military-Industrial Complex, either. Good! About time these cretins got a financial haircut..
Cretins ?
You personally may think that spending around 2% of GNP on our armed services is far too much but many in the UK think it's far too low. OTOH the things you're most motivated about may be a low priority for others - that's how democracy works.
People hate Crobyn because he dares make the world better for the majority - and not just a few priviliged rich people.
People hate Corbyn (or IMO more accurately deride Crobyn) because he is entirely ineffective at making the world better for the majority. His tactics are forty years out of date and his lack of charisma means that he is unable to inspire and motivate MPs in his own party much less a majority of the UK population. Sure he has a hardcore of supporters but then again so does Middlesbrough FC.
If he was a dynamic and charismatic leader proposing new and innovative ways to address the chronic lack of economic and social mobility in the UK, the increasing levels of income and wealth inequality and the range of societal challenges of the 21st century then he'd be doing far better.
Instead we have someone who never really left the sixth-form common room fighting the battles of the 1970s with the tools and techniques of the 1970s. He's as outdated as an ash-framed Morgan motor car and has the same niche appeal.
