Well, obviously cheaper goods are bad for Americans. When Americans save money it's bad.
When the Japanese lose money to sell us cheaper goods it's obviously good for Japan.
You just don't understand economics. We need a tariff to stop Americans from saving money.
They only lost money the short run while they fought to gain market share. Once they acheived dominance of the oligopolistic consumer electronics industry, they raised prices and profited hansomly, as they continue to do until this day. MITI is always ready to step in when someone threatens their entrenched position, so no one attempts to dislodge them the way they did to RCA and their other American competitors.
You're obviously not familiar with such concepts as economies of scale and oligopoly. You need to take a class in industrial organization.
