It's not always that simple. I couldn't afford to give up work/ potential career advancement / pension contributions but when it felt like the only option for my DS when he refused to go to primary.
A few years later with 2 young homeschooled DSs in tow, my marriage failed and I found myself a single parent trying to manage it all.
I had to be creative since I had given up my career when the kids were young too. I retrained doing an online masters degree, worked part time evenings and weekends when the kids were with their dad, or got babysitters.
I continued to homeschool as the kids were part of an established community by the time I broke up with my ex and didn't want to disrupt their lives further.
It has been exhausting but they are now 16 and 18 and I am almost at the end of my home ed journey.
DS1(18) did really well with his GCSEs, which I had to pay for privately, and after nearly 2 years at 6th form he should be off to uni soon. DS2(16) has already done 5 of his GCSEs, grades so far are 4 x 9s and 1 x A. Has 3 more exams to do this summer and then he's off to 6th form to do 4 A levels.
I don't know if it was the right decision, for me it was a massive sacrifice. But it seemed like the right thing to do at the time. Most home ed parents have a mix of ups and downs, as do those whose kids go to school.
But I certainly wouldn't call it a privilege, there is no way I could have afforded private school, we just lived quite simply. Money went on the activities they wanted to do, but a lot is organised cheaply among home ed families. Tutors have only been used minimally for a couple of subjects near exams, but mostly, like others have found, GCSE textbooks have sufficed.
I am fortunate that I eventually remarried and things became easier then. But I had 5 years as a single, part time working, home ed parent. And believe me, I did not feel privileged.
