Explain this construction shit

[OAS]

You can thank your union for that. Supply and demand of skilled labor works in every other industry, it would work in yours if the union didn't tie the industries hands. You have to know someone in your line of work, that does the same job you do that just sucks at it. Don't you shake your head wondering how that worthless f makes as much as you but they have no clue as to what they're doing. Don't you feel you work twice as hard, twice as smart, twice as effective? But what value do you get in return that the worthless f doesn't get?
