I agree here that much of what Americans and Europeans call their GDP is fluff. Our service sector is very fluff ridden. In the US, we have a 100 million dollar lawsuit that one side wins. This 100 million is counted in our GDP? I know that the labor and billing by the two opposing sides of lawyers teams will be.
Transfer payments are not counted as part of GDP, the market value of all final goods and services produced within a county during a specific time. You are correct the labor services etc by the law firms involved is counted.
