Call it what you will, incentives are what get people to work harder.
If you cannot catch a bird of paradise, better take a wet hen.
If you feed the people just with revolutionary slogans they will listen today, they will listen tomorrow, they will listen the day after tomorrow, but on the fourth day they will say, "To hell with you."
