Thank you. It lessens the impact of the article somewhat, but not entirely.

Please tell me how (since you're here now, mate) we can understand the meaning of global GDP so that we can grasp whther that is spending money for making changes or just the income we live on. Can you make a metaphor for me to understand with? Economics is a dirty magic and I have trouble with its basic concepts, I'm afraid. If we have 85 B as GDP, what is left for global projects and how do we even enact global projects?
