Who cares how much the drivers get paid, surely the comparison is how
cheap it is for the passengers?

The overall costs of operating the system, of which staff wages are a
majority part, will depend on the prevailing pay and cost of living in
that country, so it is an important part of the issue.

Ukraine wages are as far as I'm aware
very roughly 20% those of western europe for the same job.
So for a fair comparison multiple the Kiev metro fares by 4. So that'll
be
25p for a single.

30p, please; 20% means multiply by 5. However, it's really not that
simple. There are other costs to consider.
