Over in the USA it seems that the case for wealth - and its benefits to us all - is being made:
Conard picked up a soda can and pointed to the way the can’s side bent inward at the top. “I worked with the company that makes the machine that tapers that can,” he told me. That little taper allows manufacturers to make the same size can with a tiny bit less aluminum. “It saves a fraction of a penny on every can,” he said. “There are a lot of soda cans in the world. That means the economy can produce more cans with the same amount of resources. It makes every American who buys a soda can a little bit richer because their paycheck buys more.”
And the people create that consumer benefit should be allowed to make - and keep - their wealth.
