Playboys are shudras

To be a playboy in this life is unfortunate because too much attraction to women will lead one to fall into the association of sudras, who can easily take advantage of mingling with women without restriction. In this present age of Kali, when people are mandah sumanda-matayah–very bad because of a sudra mentality–such free mingling is prominent. Among the higher classes–brahmana, ksatriya and vaisya–there is no chance for men to mingle with women freely, but in the sudra community such mingling is open. Because there is no cultural education in this age of Kali, everyone is spiritually untrained, and everyone is therefore to be considered sudra (asuddhah sudra-kalpa hi brahmanah kali-sambhavah). When all the people become sudras, certainly they are very bad (mandah sumanda-matayah). Thus they manufacture their own way of life, with the result that they gradually become unfortunate (manda-bhagyah), and furthermore they are always disturbed by various circumstances.
