You're absolutely correct. There's no point in trying to defend the company from something they clearly are responsible of. Part of my argument is that perhaps the investment is there, it's just that we cannot see it all in front of our eyes.
Between Next Gen, Carsland, New Fantasyland, Shanghai, Ratatouille, DLP overhaul, Mystic Manor, DL's Fantasyland refurbs, Avatarland and DHS presumably going through a big renovation process, the investment is there. It's just that such changes are not that visible for us because the budget is a lot more spread than at TDL.
Not to underestimate OLC though. It's undeniable that they do a fantastic work managing their parks.
