Thirukkural 530

உழைப்பிரிந்து காரணத்தின் வந்தானை வேந்தன் இழைத் திருந்து எண்ணிக் கொளல்.

Uzhaippirindu kaaranatthin vandhaanai venthdan Izhai thirundu ennik kol

A ruler must regard a man who comes from toil and hardship with the same measure of respect as one born to rank. Judge him by his conduct, not his origin.
