Srimad Bhagavatam Canto 12, Chapter 03, Text 35

SB 12.3.35

panayisyanti vai ksudrah
 kiratah kuta-karinah
anapady api mamsyante
 vartam sadhu jugupsitam
 
Translation: 
 
Businessmen will engage in petty commerce and earn their money by cheating. Even when there is no emergency, people will consider any degraded occupation quite acceptable.
 
Purport: 
 
Although other occupations are available, people do not hesitate to work in coal mines, slaughterhouses, steel mills, deserts, floating oil rigs, submarines and other equally abominable situations. As also mentioned here, businessmen will consider cheating and lying to be a perfectly respectable way to do business. These are all symptoms of the Age of Kali.
