Nice to meet you <a href=" http://iorarua.com/iorarua/index.php?descriptive-beach-essays#illness ">help me solve this math problem</a> Important point, it&#8217;s not so much about the absolute level as it is about the longer term direction. Yes we had tariffs 100 years ago, and yes we had world trade. We could raise tariffs tomorrow and we&#8217;d still have world trade. Changes happen and businesses adjust and a new equilibrium is reached. If we were to raise tariffs, we&#8217;d import less (and stuff would cost more), we&#8217;d also export less (and people would lose jobs) and net-net, we&#8217;d lose.
