Final answer:
Profits drive the sales of industrial goods by motivating businesses to improve their products and increase their operations.
Step-by-step explanation:
In a competitive market, profits play a significant role in driving the sales of industrial goods. When businesses have better or cheaper products, they can increase their profits. In turn, this motivates them to expand their operations, build new factories, and attract new firms to enter the industry. On balance, the gains from these profits outweigh the losses and contribute to the overall economic success of a nation.
