benefits are ofcourse low cost living, weather, people etc.. You live here and use infra and ofcourse you pay contribution to society. Tourist who visit here week or two leave huge amounts of money here and run this country. It's your decision if you want live here and pay taxes etc..
where is no taxes? Here is very low taxation! Starting from zero to maximum 30% even if you earn 100mil month! I have residency and business at lower taxed country too but there's is no free healthcare or tax funded schemes and systems like here in Thailand.
If you are here legit with non immigrant visa and pay taxes then cost is max 750baht month. Company pay other half. If you stop working and pay ~15€ monthly it's rest of your life including all benefits what citizens get👍
