YABU. You started too late and therein lies the problem. My parents did my homework with me every day when I was 5/6 by the tone I was 8 it was all self directed and they didn't have to do anything. Occasionally I would opt not to do anything but most of the time it wasn't a problem. The earlier you start the easier it is
Again though, depends on the child. I sat and did homework from before i can remember. It actually led to me being being bored and able to completely disengage at school, reading books under desks, yet still keep up.
As i got older I grew to resent getting home from school and being made to do more school. So I thought up ways to avoid it- using the same techniques i avoided work at school too. Then an utterly shite secondary school meant I was never able to re-engage properly, despite wanting to and having the parental support.
I think it is very tricky to get it right. For every parent who says “i did this and it worked” there will be 5 who did exactly the same and it didn’t.
As pp said it needs a home-school-child triangle. It isn’t one more than another.
The race to gcse/a level/uni all seems a bit daft to me. Some kids may learn differently, or need a little bit longer to mature or absorb learning. Why do we make everyone sit gcse’s at 16 then move them on? Why not let those who haven’t found their groove, or are maybe less driven, or less able, to sit them at 17, 18, or later?
Out of interest, where would a 19 year old who wanted to take a full set of gcse’s go? Is there provision these days? Back in my day you sat them at 16, maybe resat mathes/english the following year if you didn’t get your C, then that was it. If you wanted to return to education it was night school, open university, or access courses, usually around a full time job.
