I discovered last night that you do get a minimum of 1gpt. So the correct answer to the original question is 8gpt.
At this point it's not a matter of if we will win the game but when. There are certainly needs in the ICS cities, of which there are very many, but there are also needs to workers. So I just need to farm a balanced amount of wealth, mix in scientists and revenuers and pop the occasional worker.
Thanks for the input. Mystery solved.
