Speaking as a Chartered Tax Advisor, a few points:
Scandinavians pay much more income tax across the board. If you want Swedish services, you’d be looking at 30% + basic rate, not 20%. Is this still popular. Corbynomicsof getting Swedish services by just taxing higher rate tax payers is wholly unrealistic.
We live in an international business environment. We can’t do anything about that as an individual nation. We need to work with other nations to ensure Amazon / Starbucks / eBay etc pay a fair about of tax in the UK. We are working with other nations to achieve this. It takes time. Ditto fat cats with overseas bank accounts / Philip Green / Richard Branson. Until we change international taxes, working with other nations to do this (which we are doing) the only thing we can do is vote with our feet and boycott their stores / services.
I bought a house recently. Paid an absolute fortune in stamp duty from a man who had lived there 50 years. My stamp duty was from my earned income, and was equivalent from the money I earned in the first four years of my working life. The money I paid the seller was 99% profit to him due to house price inflation and was in no way taxed. It might have been a more efficient means of tax for him to be taxed on his profit rather than me being taxed for choosing to move house. We need to look at taxing wealth more.
Triple lock pension is totally unaffordable but it is politically unpopular to change it.
None of the doctors I know work full time as they are paid well enough to live nicely off part time earnings. I don’t think increasing their pay will help the NHS. Nurses, care workers etc though surely deserve more.
It is wrong to think the wealthy in our big banks etc dodge tax. They pay PAYE like the rest of us. Boutique hedge funds etc are a different matter.
I’d like to pay more tax for better services but no political party offers a realistic means of achieving this. Hopefully a more “centre ground” Labour Party might work towards this.
