"We do not need a magic money pot, roses. All we need is for people to pay their fair share of tax, and to pay decent wages." - and that on its own will do it?
No, it won't.
Of course everyone should pay their fair share in taxes, of course everyone should get decent wages. If those in work get decent wages they won't need benefit top-ups. If there is more tax coming in, then there is more in the kitty to help those without an income, for whatever reason.
But that on its own is not enough on which to build a country where everyone is fully employed and getting those decent wages.
The government doesn't provide jobs. They are created by employers, or by self-employed individuals working for themselves. There is a balance to be kept between what is good for the employee and what is good for the employer.
There are small to medium sized businesses, and then there are multinationals.
Small to medium sized businesses are rooted in this country. They can't take themselves away, so if they are not making enough to employ more people to take on more work, they stay as they are and don't grow bigger to employ more. It is a circle. Some small employers on Gn have given their views on that, and on the vast amount of paperwork they have to do.
Multinationals have their pick of locations. "Fair is not taking your money and jobs away just because you are asked to pay your fair share." but multinationals are not in business to play fair. They are there to make money for their shareholders. They don't say openly that that is why they are transferring their operations, of course. They are "rationalising their production" or "outsourcing" or "investing in a developing area" - where the workers are happy with peanuts and the authorities with a few hefty "donations".
If you rely heavily on firms with global interests to provide jobs, then you are competing globally to attract them to be based here. Less reliance on these vast corporations and a great deal more support for home-grown industries would make a steadier economy, and that would help take out the peaks and troughs that dump people into poverty.
