I guess I'd put the blame on the amount of posts I read every day and the attitude towards new goblins, which is "You should do this". What they need is a proper education in gold making, they need to understand the process, and not learn about new sources, cause then every time a source dries up, a farm is nerfed, they come back here to ask the same question. "This died. What now?" or "I'm at 500k, what now?" And that's why I'm annoyed. But then again, to each his own, I'm not the one in need of help...
Just kidding, but yeah people just need to actually look at market and if they have the slightest interest of making gold, there are tons of options. But people basicly want 100k gold per day, without having to research for that niche and neither do they want to take long. I honestly wouldn't even bother helping someone that doesn't put the slightest effort in.
Professions skills are split between expansions now, you'll have a separate skill bar for each expansion. There are still 950 profession levels in total, just that there is no one single progress bar with 1 to 950 for it anymore. Instead, there are 8 separate progress bars. (The only exception is Archaeology, because it will still have a 1-950 progress bar)
The thing I liked best about the wide shuffle of those days was that it made ALL of my alts feel valuable. I'd get some ore some was sent to the miner to be smelted and then on to the blacksmith for belt buckles. The rest went to the jewelcrafter to prospect. Some of those got cut, the rest got turned into jewelry that was either sold or disenchanted. The enchanter then converted those mats into scrolls. Meanwhile the army of alchemists transmuted that expansion's elemental material (volatiles, sorcerous, etc). It felt like a whole business operation.

All of this is to say that while you make some good points, such as not trying to farm what everyone else is farming, look for other opportunities, it's not always as simple as just going back to old content. I've heard from many others on this subreddit over the years that the examples I show above are neither unique to my server, nor are they new problems. This might be part of why so many people are expressing difficulty in finding their way.
In a few months only mats will be worth anything. At this point we have people with tens of millions of gold and people with just a few thousands. A flask takes tons of mats to make, and they will sell for well over 10k gold each, so the casual players won't afford them. When people realize that the rich guys will always take buying from the AH over farming their own mats, the prices will go even higher, then casuals will notice how expensive flasks are, and they will pick up alchemy and make more flasks, driving the prices down again.
