if you believe in Welfare, you must believe in taxation and I presume you believe in some sort of sliding scale, so that seems moderate, just a matter of who pays how much
What should the Welfare do though?
Supporting people to work their way to independence rather than keeping them dependent
I believe in taxation, but I also believe that once you start taxing at 40,50 or 60% on a portion of earnings, two things happen. Firstly, some people are demotivated to earn more so entrepreneurs (that in turn may employ people) stagnate or cut back as the extra effort isn't worth it. Secondly, they will try to fiddle the system.
Have a higher personal allowance of say 20k, then say 20-60k is 25%, anything over 65k is 35%. Scrap the stupid lower tax on dividends from your own company (as that just encourages business owners to pay themselves up to the threshold and then take the rest as dividends). What this will do is stop people from doing cash in hand jobs so more will be declared. remove a level of bureaucracy to business owners (as a lot less of their staff will have to pay tax) and encourage people to try to earn more as they will keep more. If you keep more, you spend more.
Studies have shown (I have no source, this is from memory of a year or so ago) that overall the government will collect about 10-15% more in taxes with lower rates and higher thresholds.
^^This is my right wing stance to generate the taxes to pay for the Welfare and National Health service. Welfare should be there not as free money but to help and to encourage those that can work to try to get back on the payroll. Those that can't through sickness, disability etc should be fully supported.
There will always be those that abuse any system, but by encouraging people to work by letting them keep more of what they earn will boost the public coffers and also make sure welfare goes to those that need it, not those that don't want to work or simple are caught in the trap where they are better off not working. There is no silver bullet, the way the tories have acted over the last few years has made people resent anyone who earns well and gives out the "tax those that earn well as they can afford it and are all fiddling anyway" feeling.
Then you have public services. These IMO should be amongst the best paid jobs as they are the jobs that keep the country going. The old 'oh the NHS is so inefficient' is IMO true. If we could somehow cut the waste (I know, I know, Tory PPE etc), maybe that money could go to the infrastructure and the staff to make people proud to be doctors and nurses and want to be one again.
The problem is I feel is that everyone has different views on different things and only lean one way in general to the other. The one party fits all doesn't work and never will. Maybe we need a coalition government with Labour and Conservative - a true 50/50 government so each side could keep the other in check. It will never happen and never work, but possibly the only way to keep everyone happy.
There are probably so many holes in my arguments, but to be fair this is probably the first time I have actually thought about it like this.
