My wife is an MA, from a good Uni, in Early Learning..

She's got 35 years experience teaching nursery/infants
in schools in 'disadvantaged' areas.
Parents with poor education and low aspirations.
Crime and drug related social and mental issues.
Cultural attitudes hostile to self-discipline and learning
Social media political brainwashing that teachers are marxist feminist enemy
who are plotting to demasculate boys..etc ..etc.. etc..

The kids are not blank slates by the time they start school..

As a caring dedicated [so far, not burnt out..] teacher,
she does as best she can to start them off in education...
