Economic development matters. We can't say Thailand is better than the US in every way that matters when it's a much poorer country than the US.

Of course, maybe Thailand is better than the US in some or even a lot of the ways that matter, but not all of them.

GDP per capita (PPP):

Thailand: 26323, USA: 89105

GDP per capita (nominal):

Thailand: 7767, USA: 89105

Human Development Index:

Thailand: 0.798, USA: 0.938

Being a rich American with a top US salary and living in Thailand mitigates many of the downsides seen by poor Thai.
