The strongest objection is a sound one, so take it first. Income from capital is not untaxed. A company pays corporation tax before it hands over a penny, and the shareholder is taxed again on the dividend, so the headline rate understates the real bite. Capital is mobile in a way labour is not: tax it too hard and it leaves, and the investment goes with it. And the remedy usually demanded - an annual tax on wealth itself - has a genuinely poor record. France, Sweden and others tried versions and found they raised less than promised, cost more than expected, and fell hardest on the moderately wealthy who could not afford the advisers the truly rich employ. As an instrument, "just tax the rich more" is mostly a way to raise little and distort a lot. All of that is true.
It is true, and it leaves the structure standing, because the structure is not about the rich at all. It is about the gap between two kinds of income. And the gap is stark. Earned income - the wage - is taxed immediately, in full, at the highest combined marginal rates in the system: income tax up to 45 per cent, employee national insurance on top, and a further employer charge the worker never sees on the payslip (HM Revenue and Customs, 2025/26). Income from capital is taxed later, and lighter - a capital gain at 24 per cent, a dividend at up to 39.35 per cent - at a moment the holder largely chooses, and through wrappers built to shelter it: the pension, the tax-free allowance on gains, the family home that pays no tax on its growth. Wealth that is held and never sold is barely taxed at all. The most sophisticated estates borrow against rising assets rather than sell them, and pass the lot down having triggered almost nothing - because tax mostly falls at the point of sale, and sale can be deferred forever.
The bias, stated plainly
Line the two up and the system is not neutral between them. It taxes the thing you do with your hands and your week - work - promptly and heavily. It taxes the thing you do by owning - hold, defer, borrow, bequeath - lightly and late. That is a standing incentive, pressing quietly on every decision: earn less, own more. Convert effort into assets as fast as you can, because effort is where the tax lives. A country can decide that is fine. It should at least know it has decided it.
Why this is not a left-wing complaint
The reason to notice this is not to arrive at "so tax the rich". The instrument objection stands: an annual wealth tax is a bad tool. The point sits upstream of any remedy. The base itself is tilted, and the tilt is against labour. That should trouble the right as much as the left, and for a better reason. A right that believes in work, in earning your way, in the dignity of a wage, is defending a tax system that punishes exactly that and rewards inherited holding instead. The honest argument is not about soaking anyone. It is about whether a country that says it values work should tax work more heavily than anything else it could tax - and keep doing so by default, because no one ever decided to.
An opinion of the house. The argument is ours; the record beneath it belongs to no one.
How this piece was made
How this piece was made. The standard defences of the current treatment of capital - double taxation, mobility, and the poor record of wealth taxes - are put at full strength and conceded, so the piece cannot be read as a call for a wealth tax; it explicitly rejects that instrument. The claim is structural: labour income is taxed immediately, fully and at the highest marginal rates, capital income later and lower, held wealth barely at all, with buy-borrow-die as the endpoint. These are features of the UK system rather than contested statistics. FIGURES CONFIRMED (2026-07-18, HMRC 2025/26) before publication: the exact current marginal rates (income tax bands plus employee and employer NI; dividend rates; capital gains rates, which changed in 2024) are confirmed against HMRC 2025/26 and now stated in the body (income 45 per cent, employee NI 8 per cent, CGT 24 per cent, dividends up to 39.35 per cent). A critic should test whether the effective, not headline, gap between labour and capital is as wide as the structural argument implies.
