Telling your employee to hire a Filipino nanny cause they (meaning Filipinos) are service-oriented, and liking Japanese cars is the same? Really? Come the F on, Jesus.

Praising mastery of specific skills by nationality is the same thing. If you look down at service work might be the reason why another nationality has surpassed your own. People use to look down at nerdy computer work until pay increased and made it cool.

Telling your employee anything can be problematic. Best you never speak with them.
