I don't know what company you work for that is 'bigger than Disney',and I'm not asking, but... let me guess... you do NOT work in the public relations department... am I right???
FYI, no company in the history of ever has said/thought "GOSH, we're just TOO popular; we'd better raise prices to make it where less people come!" Disney does try to keep the parks from getting too full... it's just their definition of 'too full' is far, far different from yours. You'll notice that from time to time wdwmagic will post an article "Magic Kingdom closed due to reaching capacity" meaning they will straight up close to any further guests entering the park once they reach a certain number of guests. And what you are probably thinking is a good number of guests in the parks... well that generally happens during the time of year when Disney is scrambling to get more people INTO the parks, so they run promotions like Free Dining or 20-30% Off Resort Stays.
I'm sure Disney would enjoy the cash flow benefits of raising ticket prices if every customer was willing to pay the new prices, but not everyone would, and it would go against everything Walt wanted to make it where only the elite could afford to or feel that it's worth it to come. Sure, it would be great to see all the enhancements and improvements across the parks if they had all that extra cash, but that isn't a move they are going to ever make. So you'll just have to keep on wishin'.
And if you think the parks are too crowded when you go, well then get off your tail and do better research, buddy. Go find a crowd calendar (touringplans.com has a great one, with a guarantee) and find out when the crowds are predicted to be the absolute lowest in the year and go then. Or don't. I'm fine either way.
