Can you back that up with data? Anecdotally regular people get phished all the time, why do you think banks are sending out frequent reminders, show banners on their websites and apps about phishing attempts in the wild and mail providers explicitly showing if something is an official Google / Fastmail communication and when it's not.
When I see phishing mail they are always for banking, Google / iCloud accounts and not specifically targeted at "corporate" or government agencies.
