Thailand got spoiled. Pretty soon it will be known for sex tourism. Meeting the financial requirements is not realistic for.many ex pats. And cost of living in Thailand doesn't justify the fin requirements. I'd vote for Laos or Vietnam as 2 viable options.
Philippines is one country that I'd very *tourist* friendly. Ex-pats can stay long time. Malaysia gave me 90 days without asking (VOA). Not sure of other countries in SE Asia.
Nobody is trying to "game" the system. If tourists are spending their money in Thailannd we are helping the local economy ! Ask the local hotels and restaurants and tuktuk drivers. Make it more affordable to get a "proper" visa
