These white collar scum who occupy major corporations and government would be hung or imprisoned for life for their thievery in different times. Those in prison for extended terms besides violence and capital crimes have parking tickets compared to these criminals.
In this case, it’s not a major corporation — she founded the company after dropping out of Stanford’s Engineering school. She hyped and lied and hyped and lied to create the fake company.
