Price and wage controls are the only way to control

C My final answer. I changed it from E to D to C.

For corporate profits to be same or increase the wages should be in control and/or prices should be uncontrolled.

Case1: Now consider a situation in which wages and prices are in control. Profits will go down as productivity will be low and not enough revenue is generated from the market.

Case 2: If wages are controlled and prices are uncontrolled then depending upon the condition the company will make heavy profit or less profit as the costs are down and revenues can be maximized.

Case3: If wages are uncontrolled and prices are controlled then high cost and low revenue in which case profits will be low.

So in any case the workers will have little to spend either because of low wages or because of high prices, in which case they will find there money to be not enough to purchase something.

I guess
