I moved to Thailand instead of PH because the job market was better for me. I have toyed with the idea of starting a US business and becoming an employee and try to work-out a visa that way. The US and Thailand have some sort of treaty that gives special treatment to the US business (

However, most the people I have talked don't know anything about it and it is still a huge amount of paperwork.
As a US citizen (well most people) you can get an METV which gets you 9 months. For the first 9 years that I live in Thailand, I have had a few of those. I would estimate 6 of the 9 years that I have lived here, I have been on short term visa, doing 2 week border runs.
Philippines is good too. If you are unwilling to pay for the elite visa and unwilling to get creative with your thai short term visas and assume that risk, then most definitely you've made the choice to not stay long term Thailand.
