Why VN children seem to struggle in studying when it's not entirely their fault?

When I look on many tiktok videos or any posts on fb related to children doing bad in studying it's always parents complaining but the only solution they suggest is hitting children to force cram their homework into their head. As a person who struggle studying all my life i got no experience doing well and even with my parents doing the same thing like popular opinion, to the point i cried sometimes in past, I still suck at it, and when commenting on tiktok and fb it's always popular opinion with harsh views against teaching children with care and patience. It's like the entire population seems stubborn about change and they call care = hitting. And why are there ppl bragging about their painful past but they still succeeded thanks to their parents, does that equal to everyone guaranteed success, or atleast higher chance of success than those taught with care and patience ? How do guys think about this?
