But Thai's all pitch in, they live many to a house / room, retired farangs are alone or with Thai partners only.
Of course we have the Thai elite who we couldn't imagine ever having that sort of wealth but they are the 1% ers.
Farangs will never pay Thai prices ( don't care how long you've been here or how good your Thai is ), majority of farangs will not shop for food at the local thai markets etc, which are much much cheaper ( although mostly poor quality ).
My ball park would be 60-80k per month with everything paid for, house / condo and vehicles etc.
