[Grammar] not everyone is negatively affected by power, but it happens sometimes.

[yi-ing]

When some people get a lot of power, maybe they think that they should be making all of the decisions. However, I agree with Jane that not everyone is negatively affected by power, but it happens sometimes.


To what does it refer? Does "it" point to the whole sentence "not everyone is negatively affected by power"?
Can we replace it with "this or that"?

It replaces "someone/a person being affected by power".

Only "it" works in the quoted sentence.

Note that isn't​ is written as a single word.
