What's kind of funny is the difference in directions that WDW and DLR have taken over the past 15 years or so.
Part of the complaining is that Disney has basically spent the vast majority of it's domestic capital in California at, what seems like, the expense of WDW.
Look at DLR in 2000 and compare it to 2015. Even taking into account the failure of DCA version 1.0 they've already corrected that problem (and corrected it within 11 years) before rolling out DCA version 2.0 in 2012.
DLR has gotten a brand new theme park with arguably 5 new signature attractions (TOT, RSR, GRR, Soarin', Screamin', and TSMM) plus all of the other attractions at DCA. RSR is the signature new attraction for Disney as a whole right now. In addition, they've had 2 other E tickets significantly refurbished (SM and BTMRR) and brought back the subs (which were filled in at WDW).
By comparison, WDW in that time frame park wise has closed up significant parts of Future World at EPCOT and also closed several attractions at DHS and opened a rehabbed Test Track at EPCOT and added a Dumbo carousel, a "dark" ride, and a relatively short "family" coaster to MK which replaced another dark ride.
WDW has also implemented MyMagic+ (which DLR doesn't have yet).
Disney had plenty of money to invest in the domestic theme parks and they did spend it, they just spent the VAST majority of theme park capital spending in California.
