Protectionism - Tariffs.

How much will this interval of tariff protectionism affect? This goes by "economic communities" (it could have said countries) and will depend on the proportion of GDP that is exported. For example, in one area, phones can be produced that are purchased within an "economic community", plus an amount that is demanded outside of that area. We need to see the proportion between what is consumed inside in relation to what is exported. At first glance, the Trump administration aims to produce more things domestically.
