With regard to upgrading lifestyle, cell phone yes Buick no. What I mean is that I don't believe 11 Billion people can have our lifestyle if it is produced as it is now. Just like we wouldn't have smartphones if we still made computers like this: https://youtu.be/YIBhPsyYCiM
What I like to reflect on is how different the world was in 1927 from 1947. Just 20 years!
Bruh, we've built enough cars on this planet for everyone to own three. There is no problem with everyone owning a car. The issues are that globalization is driving (no pun intended) everything to be owned by a few centralized companies in some fictitious global market (don't get me started) rather than in numerous national/regional economies. Why? Profit margin.
ARBITRAGE. It's a lifestyle killer.
When I went to business school we were taught things like "normal profit" and morality in terms of how much to charge. Nobody discusses that any more.
If Nigeria and that region were developed regionally into an economic system like the US's they would all own Buicks. As it stands now, they own a lot of cars, they just don't have A/C most of the time and just about all of them have a check engine light on...
