POGOs are not the average BPO/callcenter, and working conditions for most are far better than most jobs, even in scam callcenters (with exceptions, as with anything else).
The average scam callcenter is relatively small scale with 20 workers in it and often is maintained within "family/friends", the POGO industry is very different and it's absolutely not reflecting the reality, that's just a particular niche that is mostly managed by foreign individuals (from China, Cambodia...)
