Complete rubbish, the Thai women I know are hard workers.
My GF is very street-smart. If I get only 50% of the care she gave her father, who died recently, I will be well content. He developed Alzheimer's about two years ago, and since then has been looked after by her. Meals, washing, cleaning his house, haircuts, everything.
I'd say either your experience of Thai women is limited, or you are associating with the wrong type, to form the opinion you have.
BTW, foibles is the correct spelling.
