Excellent diagram, which clearly shows the effects of Imperialism.
The majority of the labour and raw materials come from exploited and under-developed Global South countries (since of course coffee is largely produced in poor countries near the equator) while the vast majority of profits (and tax!) are claimed by Global North countries, in the example the UK.
If there was a more even balance of power, one would expect that the profits could be distributed on the basis of hours worked, acres of land needed etc. which would see much more profit in the hands of the growers.
No I prefer to fall asleep mid morning when I’m awake and alert after two coffees
