I don't think it's the producers inherently, it's their stocks. Our entire economy is built on the moronic idea that quarterly reports on earnings are the sole indicator of how well a stock performs. This means investors pull out if profit isn't realized by about 3 months from the release date for shows and movies. This in turn means production companies can only do so much for long-term investment shows, because not showing net profit each quarter will cause their stocks to fall, and can lead to death spirals. 

No production studio wants to go out of business on the off chance that their yet-to-be-successful show gains popularity years after they finish producing it.

This is why more independent shows, such as Schitt's Creek, can do so well - the producers of the show aren't worried about stocks; they want to make a great show. This means the show is produced with a clear goal in mind, stays true to itself, and has an intentional ending, and that combination earns the big bucks in the long run.

Sure. But, most serious investors are aware that not all stock/investments are the same. Some require more or less time to realize a return. This is not new, nor is it unique to the entertainment industry. The thing is, it's the job of the producers to sell the product to the right investors with the right pitch. If a return is expected in the first "quarter"/season, that's one pitch. If it's more of a long term investment, that's a different pitch.

Long term investments are something all serious investors want in their portfolio. The sale can be done. It's been done successfully for ages. If it's not working in entertainment, then I would lay that failure at the feet of those pitching the product...the producers.
