The 2x pop growth is great during the colony rush, but at some stage you have to bump your tax rate or you go bust.
So veterans – do you have a set population level that you aim for before bumping the tax rate (e.g. a minimum of 1b/2b per planet) or is it a decision borne out of necessity – (e.g. I’m out of cash, those colonists can’t be subsidised for ever)?
My thinking is that raising tax until your approval drops to 76% is definitely an option towards the end of the colonisation phase and once you hit 4b per planet you may as well take your approval down to 41% for some serious tax revenue.
Of course high population growth has other benefits; resistance to invasion (military and cultural) and supplying troops for your own attacks, so you’d have to be careful. But in the early game, after the colonisation phase and before someone has researched planetary invasion, this must be a good way to maximise your income?
