I was under the impression that as my population grew, my taxes would grow and my Social, Militay and Research would grow along with it. Is this true or will i just have more money ion the bank, so to speak?

I have noticed on my economy screen if i slide the %-tax bar up or down and leave the individual sliders alone, i see no difference in the total amount spent on the three spending sectors as listed on the top-right under "expenses". I do see my net income go up and down, by why does the amout spent on social, military and research not change?

My question is then, does increasing my %-taxes gice me more in the way of the three spending sectors or just more money to spend?

Now a completely unrelated question that i vcould find out for myself but im not at hiome to test out and well, i guess i'm too lazy lol. If i put troop transports together in a fleet, will i have the total number of troops invade theplanet together? That is, if i have 2 - 1000 troop ships, will i attack twice with 1000 each or once with 2000 troops?

thanks
