At what level should the higher, political limit be set? Some people say that every billionaire represents a policy failure, and so they would put the threshold at a billion. There's a joke circulating on social media that anyone who becomes a billionaire should be given a trophy congratu lating them for having "won capitalism." They should have a dog park named after them, and any additional wealth should be confiscated.

The joke is funny-but a billion is way too much. To calculate the political limit, we must start by thinking about the context in which it will be implemented (we'll cover this in more detail in the next chapter). In a country with a socio-economic profile similar to the Netherlands, where I live, we should aim to create a society in which no one has more than €10 million. There shouldn't be any decamillionaires. This figure, whether in euros or dollars or pounds, roughly holds for most developed economies...
