I'm sorry to hear of your...coal. Sadly some lose out by this balance change. But as sympathetic as I am, I wish to remind you that population size does not equal absolute wealth in the real world either. Iran is about as wealthy as Sweden in absolute terms, but has 8 times the population. Ukraine is about as wealthy as Romania in absolute terms but has more than twice the population, just to take two examples.
That indeed doesn't apply to the real world, however when comparing similar regions with each other, knowing that the rebalance are based on the statistics of each region, I simply didn't expect such difference between regions that are very similar.
