A tariff is imposed on products approaching into a country. It is completed to guard industry from foreign goods being inexpensive than homebased products. Taxes are money that individuals pay to sustain the government. For the duration of inflation (bags of money in the economy) the government must tax more to give sense to the money. When there’s a recession, or little money, the government can't tax as much because the individuals don't have adequate to give, therefore boosting economy.
