[Scooby Doo] Why are such high-quality costumes and special effects so widely available and easily affordable?

Also, robotics and animatronics seem a lot cheaper as well.

Cracked.com examined the Scooby-Doo world and determined that it's in the middle of the worst economic collapse since the Great Depression, which is why there are so many abandoned buildings and even entire towns. 

Many of the villains that the Scooby Doo Gang encounters are highly educated people: scientists, doctors, inventors, etc... The economy is *so bad* that even the intelligentsia can't find work, so they're compelled to use their talents for scams and outright theft in order to survive. 

Almost all of these scams and thefts involve scaring people away from uncovering them with some sort of supposedly supernatural creature. In order to make that work, the "creature" needs to be as convincing as possible. Since the intelligentsia have both talent and free time available in abundance, they are able to create very high-quality costumes and special effects for use in their operations. 

The American Dream has unquestionably died when a guy with a Ph.D in Robotics decides that his best shot at a decent life is to create a mechanical Frankenstein and use it to extort a hotel for money by threatening to scare away all the hotel guests.
