Akka
Moody old mage.
No, I'm not starting on bonuses about fights, this has been talked about for ages and it seems there is nothing hidden here 
What I'm wondering is about bonuses on the economical system as a whole.
Let's see the situation :
Game is prince difficulty, 15 civ left (India destroyed some years ago).
I'm using my mod, but I carefully made it so AI and I are perfectly equals (I don't like bonuses for anyone, I like every player submitted to the same rules).
My empire is the big blue mass in the centre, that occupy roughly one third of the continent. Greeks are the white splash in the nord-east, who would fit easily four times in my empire.
You can see here that the Greek army is twice to three time bigger than mine (see the 110 rflemen, 27 musketeers and so on ?). They are, like me, under democracy. I'm quite a builder, so most of my cities are fully developped.
Here is the situation about technologies :
You can see Greeks do not have neither Corporation, neither electricity. I have to add they are the first or second in tech after me, so there is nearly no bonus due to tech devaluation, and I don't think they can get tech by trading.
Until now, all is fine, ok ? (though I wonder how the Greeks were able to be ONLY three-five tech being, considering the difference in size, but well...).
Now, let's see the situation a little later...
Whow ! A tank unit ?
Let's see how my tech tree allow to get to tank...
So, has they did not had electricity nor corporation, you have, to get tanks, to get : electricity, corporation, combustion, motorized construction. That's 5 techs in all.
Let's see...
During this time, they had to support an army twice the size of mine, with an empire four time smaller.
Still, they managed to get AT LEAST 5 techs. My own empire, much bigger, much more developped, and with a much smaller army to support, still can't manage to find more than 5-6 tech on its own during the same time...
And I have Adam Smith company, which means even less maintenance.
Well, I don't want to hear about tech devaluation : there is 15 civ, so when I find a new tech, the next has to spend 92 % of the price of the tech to find it, which is about the same as 100 %. So it's not a valable explanation on how they succeed to get the tech
There was no change in age, so their scientific bonus does not apply neither.
Trade ? Well, to trade these tech, they have to find another civ that discovered them too. Which would lead to the same conclusion :
HOW DARN THIS AI IS ABLE TO KEEP PACE IN TECH WITH EMPIRE BIGGER AND WHO SPEND LESS THAN THEM IN ARMY ???
Edit : now the images work, got trouble with my ftp
