That was almost 90 years ago. There would not have been a huge scandal if she had abdicated to her son once he was at least 50 and in fact many were calling for it. It's not remotely the same either because the Edward VIII abdication was not speeding up the natural succession as her abdication would have been but throwing a wrench into it.
In theory, all of this is true, but in reality, abdication was NEVER going to be an option for QEII. Her uncle's selfishness directly impacted her life in countless ways - not the least of which was her ascension to the throne, but also, perhaps more significantly, her father's relatively young death and the impact it on everyone in the family.
Even in her later years, once Charles was more than old enough, well... think about it - he would have been recently divorced at age 50, his grandmother, the Queen Mother, was still alive, his sons were still in school or just heading off to university. Charles didn't even marry Camilla until he was 56 and he was still blamed by MANY in the UK for Diana's death. It took another good 10-15 years for Charles to reach the point where British subjects didn't want to actively bypass him as monarch in favor of William. And by then, QEII was well into her 80s, so what was the point of abdication, especially since she was still fairly active and mobile.
It wasn't really until the pandemic, when she wss in her 90s, that she began to slow down and no one was going to actively campaign for her to abdicate when she was already 90 & counting - why not set the record for the longest reign, celebrate her platinum jubilee, etc.
There are lots of valid reasons why QEII chose not to abdicate - and I don't expect that we're going to see Charles abdicate either. Given his cancer diagnosis, it's going to be a short reign regardless - probably 10 years at most, maybe much less if some of the reporting I've seen is to be believed.
Now, do I think William may choose to abdicate to George if he serves as monarch for 25-30 years? Sure, I could definitely see William doing that, but there may be good reasons why he doesn't if that's the choice he makes.
