That business growth should not be an end in itself is a worthy end in itself
First we have to work real hard on our current distribution machinery since before the needs of all your citizens are satisfied, which might include even those of the other poor in the world, you would not be able to relax enough if you always had to be looking over your shoulder to see if someone is taking advantage of your bliss to grow away from you.
Second you need to send much better economic signals on where you find yourself, as I at least would not want to get stuck on a level that requires me accompany my wife when she goes out shopping at 5 am in the morning in one of those strange sales that the US economy seems to require. For a start I have often suggested that instead of only adding to the economic indicators we need to start resting some of its costs. For instance every time someone has to leave whatever he is doing in order to answer an uninvited call, offering you something he could do without, then you should automatically rest a couple of quid from your GDP.
