Aaah OK I see. I didn't fully get it.
In terms of infrastructure, I think we should distinguish universities and countries who had initiated their online transition before the COVID from the other ones. You can take Estonia for instance, where things were quite smooth.
In addition, as you said, the financial question leads to the possibility to quickly invest where needed, and we have here a plus for the developed countries. Things could however be quite slow, even in developed countries, as deploying for instance a better WIFI coverage does not take 5 minutes. In my university, they worked out things quite heavily during the last summer break, to improve the network for this year. This is however quite late relative to the pandemic. This being said, better late than never!
At the student level, I am attempted to say that the financial issue is the same everywhere in the world, as students belong (in most case) to the population with the least amount of resources: many students are indeed struggling to get food for instance. I can fairly imagine this holds in all countries.
