Mbh 3.189.3b

And Brahmanas and Kshatriyas and Vaisyas with their virtue contracted and divested of asceticism and truth will all be reduced to an equality with the Sudras. And the lowest orders of men will rise to the position of the intermediate ones, and those in intermediate stations will, without doubt, descend to the level of the lowest ones. Even such, O Yudhishthira, will become the state of the world at the end of the Yuga. Of robes those will be regarded the best that are made of flax and of grain the Paspalum frumentacea[45] will be regarded the best. Towards this period men will regard their wives as their (only) friends. And men will live on fish and milk, goats and sheep, for cows will be extinct. And towards that period, even they that are always observant of vows, will become covetous. And opposed to one another, men will, at such a time, seek one another’s lives; and divested of Yuga, people will become atheists and thieves. And they will even dig the banks of streams with their spades and sow grains thereon. And even those places will prove barren for them at such a time. And those men who are devoted to ceremonial rites in honour of the deceased and of the gods, will be avaricious and will also appropriate and enjoy what belongs to others. The father will enjoy what belongs to the son; and the son, what belongs to the father. And those things will also be enjoyed by men in such times, the enjoyment of which hath been forbidden in the scriptures. And the Brahmanas, speaking disrespectfully of the Vedas, will not practise vows, and their understanding clouded by the science of disputation, they will no longer perform sacrifices and the Homa. And deceived by the false science of reasons, they will direct their hearts towards everything mean and low. And men will till low lands for cultivation and employ cows and calves that are one year old, in drawing the plough and carrying burthens.
