Then the article presents no arguments on how the UK can achieve such a feat other than having a bit better public transport. Public transport does certainly help and it’ll increase GDP; but I highly doubt it’s the determinant in creating the richest country per capita in the world.
As for “can”, any country theoretically can become super-rich. Singapore did. Whether it will or not is another matter. The UK had particular circumstances in the 1700-1900. It does not have the same circumstances today. Lots of countries are also racing toward this goal. The UK is certainly better positioned than most countries in the world but not the best positioned out there.
