Yes it is. People forget this because they live in a bubble. It’s like remote work, nice for the laptop class, but not possible for the person growing your food and manufacturing your tesla.
We've looking into this, as deeply as we can as "outsiders". We homeschool, but are firmly "middle class" from a national perspective and easily in the top 1% income in our county.
Regardless of income, the key factor seems to be the rationale. If parents want to homeschool because they're involved with their kids' lives and want them to succeed, they'll do well relative to the available public school options.
Just like high earners like LeBron James are not allowed to WFH and have long commutes.
It just depends on the nature of the work.
