Re: Tariffs have worked many times
Tariffs worked 200+ years ago so they will work in today's global economy? You're going to have to provide some more recent evidence.
China has every advantage to be able to outlast the US. They are a dictatorship, so little political pressure can be applied to the leaders by the citizens. Tariffs are against republican orthodoxy, so there will be little appetite among republican legislators to allow this to continue once they start hearing from their constituents (it is too soon to affect the upcoming election, but if they are still in force in 2020 tariffs will take down Trump and both houses of congress)
And finally, it is a lot more difficult for US companies to leave China than it is for China to find suppliers of what they import from the US. And doing so fits in with their plans to be self sufficient - they want to encourage farmers to modernize so they can grow more corn & soybeans themselves etc. They also don't have a $20 trillion deficit like the US, but instead have a surplus (sovereign fund like the Saudis) so they can toss out cash to help industries weather temporary difficulties caused by the trade war for as long as necessary. The US can't, especially next year with the deficit projected to exceed $1 trillion (during economic growth!) so there will be little appetite for continued handouts to farmers like Trump is making to keep them on his side.
