Śrīmad-Bhāgavatam · Text 1.18.45
Who is speaking and story frame
तदार्यधर्म: प्रविलीयते नृणां
वर्णाश्रमाचारयुतस्त्रयीमय: ।
ततोऽर्थकामाभिनिवेशितात्मनां
शुनां कपीनामिव वर्णसङ्कर: ॥ ४५ ॥
tadārya-dharmaḥ pravilīyate nṛṇāṁ
varṇāśramācāra-yutas trayīmayaḥ
tato ’rtha-kāmābhiniveśitātmanāṁ
śunāṁ kapīnām iva varṇa-saṅkaraḥ

Thus they will be more attracted to economic development for sense gratification, and as a result there will be an unwanted population on the level of dogs and monkeys.
