Raising the personal allowance is massively expensive. For the same amount of money, you could look at reducing the rate of tax.

Insight: When you hear "raise the personal allowance," it sounds like helping working people keep more of their paycheck. But there's a hidden trade-off that doesn't get much attention. Every pound the government stops collecting through a higher threshold costs money—just like every pound saved through a lower tax rate does. The question isn't whether to help people; it's whether you're doing it efficiently. This matters because the choice shapes who actually benefits. A higher personal allowance helps everyone equally—the single parent and the investment banker both keep the same amount extra. A lower tax rate, though, rewards people who earn more; someone making double gets double the benefit. That invisible difference in who wins is what usually gets buried in policy debates. The real insight here isn't about the math—it's that we often treat different solutions as if they're completely separate ideas when they're actually competing for the same limited resources. In personal life, this shows up constantly: you can spend money on upgrading your phone or banking the savings; you can spend time on a hobby or on rest. The choice between two good options is usually more important than either option alone. Recognizing that trade-off—really seeing it—changes how you make decisions.
