Lower Township - Tariffs: Most other countries charge the US a tariff on goods/products that are imported into that country. On the other hand most goods/products imported into the US are not charged a tariff. The US is running a trade deficit while other countries are running a trade surplus: a surplus that may be funding their gov't programs. If they start paying a tariff to the US how will this impact their gov't programs and economy?
