lol, so in the beginning, when Civ5 first came out, the veritable trading post was available to build with trapping - very early on in the game - and immediately gave 2 gold pieces per turn when worked. Thus, along with gold coast and river tiles, it was relatively easy to get lots of money in the early game. Subsequently this was nerfed a little by moving trading posts back to Guilds, originally giving 1 gold and going up to 2 gold after Economics was researched. But it was still relatively straightforward to get gold because of rivers and coasts (especially with fish haha). Now the early game is brutal in terms of lack of gold so ... I think the trading post should be available with trapping once again and offer 1 gold per turn, going up to 2 with economics ... this would definitely help a little. Early game gold has been 'over-nerfed' and needs readjustment. As others have said, having trade routes is fine but you need units to deal with early game barbs otherwise trading is pointless.
