You seem to be confusing choices and opportunities.
Not everyone has access to further let alone higher education. Not just financially but by reason of ability.
Not everyone has access to good job opportunities - again not just financially but in terms of connections, health, confidence, access to other support (eg childcare)

I hold 2 degrees, a post grad qualification and numerous professional paperwork. I'm currently not able to work due to ill health, a combination of serious mh issues and a physical disability. I've been at various points in my life a full time low paid employee, a ft student with no other commitments, a full time employee with good prospects, a sahm, a full time working single mum, a ft student single mum & pt worker, a full time working single mum, an unemployed single disabled mother.
My brother is a police officer currently working full time, holds an undergrad degree and is working on his masters which will hopefully aid him in gaining further promotion. He's also been a full time low paid employee, a full time employee, a single pt working resident parent, a ft working single resident parent, a ft working married parent (what he is now).
The difference between us? He was born male and so was of no interest in a certain way to our abusive father, witnessed and experienced other abuse though. He also wasn't involved in a car accident where he was hit by a twat on their phone while stationery. He was also able to access a lot of support as a single parent that I wasn't because his ex died, which is how he came to be a resident single parent. Also because he had support from within the police community. Don't get me wrong, I'm very glad he and my nephew had that support just saying equivalent support isn't available to divorced single mums.
I've been luckier than others in that I was born with a brain that was able to benefit from an academic education, that same brain also has a dysfunction (possibly due to a deformity of some kind) that has led to me having severe OCD & anxiety.
I was born at a time that meant when I did my nursing degree it was fully funded
But it also meant i was a child and teenager in an abusive household at a time when such things weren't widely discussed, at a time when police policy was not to "interfere" in "marital problems" and calls to domestic disputes didn't trigger social work involvement.
Lots of choices are only available to certain people. If you're not a white, mc, physically fit & healthy male your choices will be limited. How much they're limited depends how many oppressed groupings you fall into.
A disabled, working class, woman of colour has a lot less opportunities and therefore choices than most others.
There's a reason "check your privilege" as a concept exists. Too many don't recognise, let alone acknowledge their privilege.
Having choices as a well off, mc, healthy person is not the same as a working class, disabled, single mother having to find a way to manage.
