I did same for 10 years.The assumption here is that hiring immigrants to do care giving is affordable to all. Actually, it is not. I cared for my elderly mom for 14 years and we could never afford to hire anyone. The best caregiver are family members. Family members give the best care. The best care is not provided by someone who is exploited for their cheap cost. No, I don't think cheap care givers are the best solution to fulfilling the need for care givers. It is better for the elderly to be cared for by someone who cares.
I expect that for us, with 1 child, we will hire some help prior to losing any 2 ADLs, during our deductible period before the LTCi kicks in, and the time when the LTCi aides are off.
