The median wages in Ireland vs the UK is a fair point. But how much people earn is only half the story.
The result of their much higher GDP per capita is that they have the ability to either have lower taxes - making everyone better off - or spend the money on better infrastructure and public services - that benefits everybody.
That's true, but it's also true that it's the sort of policy that can only work in a small country. Google running huge parts of their books through Ireland and paying a relatively small amount in tax is a huge benefit for Ireland. Them doing the same thing in the UK would be a far smaller benefit to the UK taxpayer simply because there are far more of us, and the subsequent drop in tax revenue from the sort of broad range of businesses that operate in the UK would mean that it would be a net loss for the treasury. Ireland, on the other hand, is massively exposed to the fortunes of a handful of huge tech companies. If they pull out, they suddenly have a huge black hole in their finances, which I'd argue is a far bigger risk than anything Brown or Blair did.
One of the reasons people are so unhappy in the UK with higher taxes is that we get so very little back for it. Our roads and general infrastructure is falling to bits. Our pension sysem is one of the least generous amongst developed countries, our health service is woeful compared to other countries, in terms of facilities, waiting times and critically, clinical outcomes. The reality is we have high taxes already AND shit public services.
And yet a huge amount of that is because those tax revenues aren't being used to pay for public services, they're being used to pay private companies to provide public services, who have consistently done a shit job and cut corners to increase shareholder profit. The other place a large amount of tax revenue goes to is paying off the debt caused by Covid and the previous financial crash. But Ireland and the UK are roughly the same in this respect, with Ireland's government debt standing at around €50k per person, and the UK's at £42k per person (but a much higher percentage of GDP because of our lower GDP per capita in absolute terms). The other difference is that the UK's is increasing whereas Ireland is managing the pay it off.
This problem has not come about overnight of course. It's been brewing a long time. It started with Blair and Brown inflating the size of the state and funding that with progressively higher taxation, and broadly the same policies have persisted - made worse in fact - by successive Conservative (in name only) governments.
We need a reset. If we are to be wealthy ever again, we need a much better growth agenda, pro-business, anti-woke, lower tax environment. Carry on as we are and we will just see progressive decline further and futher.
Potentially, but I can't help but notice when people look for examples of this being successful, they always point to various forms of tax havens with tiny populations that are basically able to fund their public services by effectively leeching off the revenues made in the more populous neighbouring countries. Nobody's made a trillion dollar company in Ireland, yet somehow all of the profits of huge American corporations are funnelled through there and that's presented as some sort of economic success story. And it is for the people of Ireland (if you ignore the insane cost of living and property prices), but it's also not something the UK can follow, because we don't have a bunch of countries that are 10 or 20 times the size next to us that we can offer to do the books for and have a free trade agreement with. Not that the city of London doesn't try, of course. The only thing that will happen if the UK reduces corporation tax (and let's not pretend the Tories didn't do it) is that revenues from corporation tax will go down.
From 2010 to 2017, the Tories reduced corporation tax from 28% to 19%. They then increased it back to 25%. I haven't looked at the effect that had on overall tax revenues from business, but the standard conservative line is that reducing the rate of tax will actually increase overall tax income, because there will be more business happening. Yet it's quite revealing that when the Tories were in need of more tax revenue, rather than reducing it further, they increased it a significant amount. Admittedly, their experiment with reducing tax was obliterated by their equally idiotic decision to leave the EU, so we might never know whether it would have worked. I don't necessarily disagree with the principle. Denmark has always operated quite a business-friendly environment, with more of the tax burden on the individual, but it is also clearly a high tax - high public services economy. Japan, on the other hand, manages to maintain hundreds of huge multinational corporations while having quite a high rate of corporate tax.
