I reckon most of the whining is simply because profit is less now than it was in the gamma. It needed to be rebalanced though.
The import/export/galaxy map data is still next to useless, as it was in the gamma, so there's no new news there and it isn't the real issue in this thread.
To make money in trading just get going, move away from the nursery set of systems you spawned in, look at the galaxy map to find a 'high tech' system (NOT the nearest to your starter system), go there. Note the buy/sell prices of Meds, Metals and Minerals (and the rest if you're diligent but just those three will be enough). Check each of the systems only one hop from that high-tech system, and you are certain to find profitable trades. e.g. the high-tech system will have meds/perf enhancers at GA - 200, and you will find an adjacent system that buys those at GA + 400. In reverse there is usually a metal/mineral that makes sense so a round-trip of 1000/tonne should be doable, enough to upgrade through your first few ships anyway.
