Trust me, there aren't as many "dummies" taking Scientology services as there used to be. Per my observations (as a former member) attendance has shrunk about 90% over the last thirty years.
The 'church' is gradually dying, as older members expire, or sneak out the back door, and younger members say "no thanks" to the cult-like practices and heavy handed money grubbing of church fund raising.
David Miscavige also destroyed the workable parts of their core practices years ago, which has resulted in a broken parishioner base who've gained little benefit from Scientology services in a very long time. That alone has caused a huge exodus over the decades.
Info on the internet probably hasn’t help.
