印度一代移民

49F + 51M first generation immigrants still working hard

We are first generation immigrants. Like everyone else in similar boat, we are always working hard. Two kids 17 and 13. My parents come to the states with me and they are in their late 70s and early 80s. Have Medicare from 15 years of working in US. But very little social security.

Currently we have 2.8m in retirement accounts like 401k Roth annuity and etc., 3.7m in VOO QQQ mag 7 and other index funds etc, 2.5M equity in primary residence and rental properties. 1M in syndications. Another 2M USD worth of overseas investments such as high end apartments. 

I am a L7 with Mag7 fully WFH and my husband is a VP in fortunate 100 company. Generally speaking, we like our jobs quite a lot. Fun subjects, flexible hours and well respected. But of course it also has drawbacks like pressures and travels. 

We are thinking about slowing down a little bit. But considering two senior parents, two kids not yet in college, we are wondering for how much longer we need to continue working this hard as full speed?
