The power struggle shows up in very small scale challenges, like
Powerpoint:forcing you to use templates, projectors, printers and so on
More seriously to use powerpoint, you need a laptop or table, the right sort of cable, an electricity, which is in short or unreliable supply in many parts of the world.
All of this illustrates that the real problem is to do with asymmetric power, hence the power struggle really concerns the fact that the rich get richer, the poor don't.
