I do very much agree with this, and it's part of why it frustrates me to see fans essentially gloating when there is a flat/negative quarter or the share price goes down. Institutional investors are not demanding less profit now in the service of a more sustainable business in 5-10 years time.
If Disney could hold the line that the nature of the business is such that there will be some quarters where revenue is flat or even a little below the prior year but it will continue to grow over the medium to long term, that would promote far healthier business strategies. That's part of the reason I didn't have any particular objection to the comments about Epic's opening. I don't know how viable that is in the current environment for a publicly traded company, however.
With more price rises apparently incoming, I am curious how worried Disney really is about the cost of a WDW vacation, at least in the short term. They still seem to be in the mode of tweaking prices here and there for different aspects of the experience rather than anything that suggests they're in crisis mode. I could see a longer term vision where increased capacity coming online in a few years time could be accompanied by an easing off on prices, but then I'm not sure even all the previously announced additions are adding that much new capacity to the parks.
