Describe Pelosi's qualifications and compare them to a hypothetical scenario where someone without relevant experience is hired for a job.
She and her family have never attended public school, have never taught nor administered any school.  Of course she is incompetent. Would a bank hire anyone who never had accounting or math lessons or who had never worked in a bank to be an account execution?
That would be as inane as hiring a family member to be part of your presidential administration if they had never worked in government.  Too ridiculous to imagine (unless the name is Trump)
