"Going to high school is her job."
The she should start demanding a wage
"Plenty of drop outs are “planning to go back.”"
You missunderstand. The swedesih system has the option for students to take a year long break, much like summer break, if they so wish
"And she’s not qualified to “point out” any problems."
And you are?
"Because she doesn’t know anything about anything."
I was unaware I was talking to Greta herself! My apologies. But seriously... How can you know that, friend?
"Including the climate"
What she learned at school in an education system far supirerior to yours is definetly enough to know that not enough is being done to combat the Climate Crisis
"And certainly not Coronavirus."
No one claimed she does. Though you need not be an expert to critizies Coronavirus messures. People on this site do it all the time and I doubt any of them are Virologists or Biologists.
