GDP is too simple to tell the performance of one economy

Consumption is everything, it is the most important part in the GDP function: GDP=I+C+G+(X-M). Without consumption, there will be no markets, because markets are there for consumption. Moreover, investment and government spending is used to boost the consumption. People need money for consumption. I believe, consumption should always be encouraged. In terms of evaluating one economy, I think consumption should weight more when we are calculating the performance of the economy. Government spending should weight a bit less, because some of the spending will not be added directly to the market. Exports and imports should be put into more categories. Raw materials and final goods will have different effects on the economy. When evaluating one economy, simple addition and subtraction cannot give us an overall picture about how the economy is on the right track, we need to evaluate the impacts of all different parts.
