It matters because Government can basically do three types of activity: it can own, it can spend, and it can regulate the property that it either doesn't own or hasn't taxed off the rest of the country. We have pretty good oversight for Government ownership. We monitor, and often get very disappointing results, I have to say, for the returns on businesses and assets that Government owns. Government is a terrible owner of assets, but at least we're fairly good at reporting on it, and we know where Government is falling short. We have one of the best regimes in the world for oversight of Government expenditure. Thanks to Ruth Richardson and the Fiscal Responsibility Act, now part of the Public Finance Act, we have good oversight of how much Government is spending. Some of us would say that it's too much, but nevertheless we have good fiscal rules, and one of the implications of that is that we have a very strong political bias against Governments that run deficits, because of the transparency.
