I use a ton at this point in the game. Especially with Meritocracy gone. That culture per trade route is important to me. I love Trade Confederation. I prefer Market Economy, only problem is Capitalism is not on the way to where I want to go (dead end tech) which is either globalization or social media depending on my victory I'm aiming for.
I use the Trade Confederation policy a lot, too. I usually only use domestic trade routes if I want to lay down some roads internally and can't do so by sending international routes across my territory. Then later on, I'll direct trade routes from my spaceport city to wherever it can get the most production.
For most of the game, the extra culture and science from trading internationally is what I'm after. Plus gold is more flexible than production. Granted, food is more valuable now that the loyalty system encourages an early build up of border cities, but clipping through the civics and research trees is still pretty useful.
Trade Confederation is excellent if you're a commerce-based Civ with lots of trade routes, relying on gold purchases. That extra culture and science is just stacked on top of the money you're making.
Hmm, surprised to see so many disagree here. The numbers just seem really awful when you compare it to just about any card at a similar civic level.
Even if you do use commercial districts and international trade routes heavily, it's still generally a max of 2 yield points per city.
Basically every other econ card obtainable at the same time easily gives you 3+ yields per city
Considering it both gives you less yields and less focused yields, and requires a specific, generally unoptimal way of using trade routes, I really don't see the appeal. I can only ever justify it if there's really just nothing else for that slot, which is rare for yellow cards.
