GDP = C + I + G + (x - m)

Where:
- **C** = Consumer spending
- **I** = Investments (business capital spending)
- **G** = Government spending
- **x** = Exports
- **m** = Imports

GDP is a country income, ignore business to business activity 

What matter most is real fixed private investment. This is where you get factories, tools, computers, machinery, AI, and all other forms of technology and productivity-enhancing devices, software, etc. It’s the source of real wage growth, medical advancements, better quality of life, higher standards of living, ect...
