My cousin is an elder and he is on disability from the age 28. He never worked physically, but has plenty of time to milk welfare, free housing while doing all this field work for the least +/-25 years.
Elders in my KH was investigated for welfare fraud couple years ago. He and his wife claimed no income, so they got government housing and allowance. They both are active JWs with field service. However, they had under the table illegal income which was eventually traced by the tax agency and were charged with fraud. The city kicked them out of the public housing and they were also tried to run away to foreigner country. I could ask my mom how many of JWs in her congregation are on welfare and are capable to work.
