The actual reason BF rates are plummeting is due to lack of access to proper support for BF.
Midwives on wards are so over run and Post Natal wards are so understaffed that there is no one to help a struggling mum BF. It's even harder to access that support once you are discharged from hospital.
Recovery from birth is hard and many hospitals now discharge as quickly as possible (sometimes even same day). So then you have a new mum, recovering from birth sent home and struggling to BF. Midwives are not all trained to check for tongue tie and in some cases the tongue tie is not considered severe enough for NHS intervention.
I know many mum's who turned to tik tok and instagram for help. Faced with all these lovely serene stories of peacefully BF babies. Huge misinformation. Only learning about cluster feeding on tik tok and insta.
Then there is the back to work drive. Most companies want mums back after 9 months to a year. Dad's get a couple of weeks paternity and that's it. A mum struggling with BF needs lots of support, some babies BF for over an hour and there is no-one to help mum.
The lives we lead now, many many new mum's live a distance away from family. So many no longer have "the village" of the olden days. So you have mum, sat along BF for hours a day, wondering if she's done anything wrong.
If anyone really wants to improve BF rates, they need to invest in proper post natal support, proper BF support services, get midwives properly tongue tie trained, allow dads longer paternity leave. Set society up so new mum's have much more robust support systems around them. However that takes time, money and thinking which doesn't exist for "women's health issues". If men were able to BF, I can guarantee the whole support services around them would be entirely different.
