According to Osho, no person or party 'brings' socialism; it arises naturally when capitalism fully ripens—like youth turning into old age. The shift occurs by itself once two conditions mature: an abundance of wealth and the replacement of human labor by technology. Forced, premature collectivization backfires; patience and technological advancement allow a humane, sustainable socialism to emerge.
Nobody makes socialism happen; it shows up by itself when society is very rich and machines do most work, so don’t try to force it.
