The guys that worked hard deserved the money that they earned.
In construction, when you did "Piece Work", it was the same thing. Some called it Target Hours. If the roof paid 16 hours and I did it in 12, I got the 16 and moved to the next house.
There were jobs I worked where I made more than the foreman. One job I had would put you on Target Hours but if you beat the time, they told you that you were now paid hourly. One guy was really fast and when they said they'd switch to paying him hourly, he slowed down the pace. THAT right there is a perfect example of Capitalism VS Socialism. If the incentive to make more than the other guy is eliminated, the desire to work harder often goes away.
