EP 88: What is GDP growth and why should anyone care?

The Mindcrime Liberty Show discusses GDP and the problems surrounding its calculations and use. Is GDP useful? Is much of GDP growth illusory especially that which is created by finance and central banks? Is the wealth of nations impossible to calculate and compare? Is calculating the wealth of nations harmful and only done for malevolent reasons? Would private product remaining be a more useful statistic to calculate? What are the problems associated with this? What would be a better way to calculate the "wealth of nations"?
