When this country started to be flooded with cheaper merchandise driving manufactures and other businesses OUT of business because these importing countries had a lower standard of living than we have, former administrations failed to raise tariff out of fear.
Now Trump is acting. Perhaps his tariff raise is too much to be acceptable to some other businesses that will need to raise prices to consumers or reduce overpaid management and reduce their internal cost. Every action taken always affects someone negatively.
Big problems our President has inherited. He will be a worn out man by 2020 and will not run for reelection. I expect a divorce in 2021 as his younger wife will want a more social life than politics which he will not be able to get off his mind.
I know as you can tell by my blogs, 26 years after my retirement.
