The author of the OP doesn't know jack squat about economics. Sales at the firm where the wages are raised do not go up. They go down. Higher wages means they have to charge higher prices for their products. Every first year economics student learns that sales volume is determined by the laws of supply and demand. The higher the price, the lower the volume of sales.
People who spout the kind of logic in the OP are nitwits who don't kusw the first thing about economics. They are ignorant and therefore susceptible to leftwing propaganda.
You have a lot of energy, but zero economic knowledge. You even just contradicted yourself. First you said >>
"Higher wages means they have to charge higher prices for their products" Then you turned right around and said >>
"The higher the price, the lower the volume of sales." HA HA HA
. Well, look at that. I don't even have to refute you. You just refuted yourself.
If the firm charges higher prices, as you advised, then they will suffer a lower volume of sales, as you just said, So is that why they would charge those higher prices ? So they can then get a lower volume of sales ? The reduction in sales is exactly WHY they CANNOT raises prices. You're making this too easy for me.
