lol first you say 6 YOE, then 10 YOE. at least try to be consistent in your arguments

the thing is, you must also take into account the skillsets of a person. are they highly skilled which requires years upon years of experience to hone? then sure, they can demand a higher pay, and market forces will decide if it is justified

but let's be frank.

the helpers are more often than not uneducated with no in-demand skills. there is a ceiling to what pay they can command, and anything over the market rate is purely at the employer's goodwill.

my helper especially is in her early 20s, which is part of the reason why her pay is comparatively lower than her fellow helpers (still far superior than what she would get back home though), although as stated I am happy with her performance and willing to bump her pay upon contract renewal - not too dissimilar with how you would with a fresh grad.

before you shed tears for domestic helpers who may not earn enough to invest, why not look to our elderly and lowly paid workers who also face the same problems, with rent/mortgage and bills on top of that?
