Tax Quality Over Quantity
What matters is not the tax rate but what the tax buys.
Chang reframes the tax debate by holding up Paraguay against Germany and Denmark. Paraguay charges a top income tax of 10% and a flat corporation tax of 10%. If low rates were what mattered, every rich person and corporation would move there. Almost none do, because the workforce is poorly educated, infrastructure is weak, and the legal system does not work well. Companies choose to pay 30% in Germany and individuals choose to pay 50% in Denmark because the spend buys things they value.
The framework forces tax debates to consider the spending side. A high-rate jurisdiction with strong services can outcompete a low-rate jurisdiction with weak services for the kinds of capital and labour that produce long-term value. The mistake is to treat the rate as the entire question.
Applied to the UK, Chang argues the country's apparently high tax burden masks two structural drivers — the 2007-08 bank rescue and the pandemic — that should be analysed separately from underlying choices about service quality. The right question is not 'is the rate too high' but 'what are we buying and is it worth it'.
- Tax is a price paid for a bundle of public services and institutions.
- Low rates do not attract capital if the bundle is weak.
- High rates do not repel capital if the bundle is strong.
- Tax debates that ignore the spending side are incomplete by design.
- Some of a country's tax burden may be one-off, not structural — separate the two.
- Reject rate-only framingWhenever you see a tax-cut argument that does not mention what is bought with the tax, mark it as incomplete and ask what services are on the other side of the trade.
- Run the Paraguay testTake the proposed lower-rate jurisdiction and ask whether capital actually moves there. If not, the bundle on the other side matters more than the rate.
- Map the public-service bundleList education quality, infrastructure, legal certainty, healthcare, safety, and public space. These are what the tax is buying.
- Separate one-off from structural driversChang argues much of the UK's recent tax burden traces to the bank rescue and Covid spending. Strip out the one-offs before judging the underlying choice.
- Look across the whole spending stackIf healthcare costs feel high, check whether under-funding social services is pushing demand into healthcare. Adjust upstream rather than just adding tax for the symptom.
- Audit the tax base, not just the rateLook at corporate tax-haven leakage, low property-tax rates, council-tax bands frozen at 1992 valuations. These broaden the base without raising the headline rate.
Paraguay charges a 10% flat corporation tax. Germany charges around 30%. Companies still choose Germany because the workforce, infrastructure, and legal system make the higher rate worthwhile.
Denmark's top income tax is around 50%; Paraguay's is 10%. Wealthy individuals stay in Denmark because the social services, safety, and quality of life are dramatically better.
Chang cites council tax bands set against 1992 property valuations, which lets a £100m Kensington home pay broadly the same rate as a Wakefield house.
Chang uses the Paraguay-versus-Germany-versus-Denmark comparison whenever people argue that tax cuts in themselves are growth-positive. The example is engineered to make the spending side of the equation impossible to ignore.
