Well they are already supposed to be paying high taxes, they just have the means to pay for specialists to help them avoid it! That won't change if you raise taxes, they'll just move their money out of reach!
There is no point ducking the issues, there needs to be investment and/or nationlisation in British industry so that the population has the opportunity to train and get meaningful skilled jobs with prospects. The more people in the country who have better paid jobs and the better British owned companies perform the more taxes available to the government.
Ever since the Thatcher and Reagan era, successive governments have viewed "investment" as a dirty word. All they want to do is sell off anything of value to private companies to make a quick buck. The problem is they are running out of things to sell now.
Eveything they privatised is run at the lowest cost possible and their staffs wages have been driven down and down in order to maximise profits. This has resulted in terrible service, poor performance and crucially less taxes coming in to the coffers. Nothing has improved by switching to private companies.
I mean this is just my thoughts obviously. At the end of the day I'm a Northerner! You might expect us to have these views as we have been decimated up here by the loss of our once proud industries and we have never recovered. Other countries have nationalised or subsidised industries, there is no good reason why we should be any different.
I'm old enough to remember the mining and ship building industries of the North East. All dead now and they didn't have to be. Tyneside built some of the best ships in the world. All that skill base has gone. We used to make the best tanks too but they shut down the Armstrong factory after the Challenger 2 stopped production. We could do with that industry right about now with all the threats in the world these days. So short sighted!
