πŸ’Ž On the danger of only evaluating projects on what is easy to quantify

A question was given to a bunch of engineers about fifteen years ago: How do we make the journey to Paris better? They came up with a very good engineering solution, which was to spend Β£6 billion building completely new tracks from London to the coast and knocking about forty minutes off the 3.5 hour journey time. It strikes me as a slightly unimaginative way of improving a train journey to merely make it shorter. Now, what is the hedonistic opportunity cost of spending Β£6 billion pounds on railway tracks? Here’s a thought; what you could do is employ the world’s top male and female supermodels, pay them to walk the length of the train handing out free ChΓ’teau PΓ©trus for the entire duration of the journey. … At which point you’ll still have about Β£5 billion left in change, and people will ask for the trains to be slowed down.
