WOTC - Tariff and protectionism

I asked this question in the Wisdom of the Crowd:

Is tariff and protectionism good for a country?

Here are the responses: (59 Votes)

44 % - It will make the country more costly and less efficient.
31 % - It allows the country to protect jobs 
15 % - It can replace VAT/ GST
10 % - It allows the government to collect revenue to reduce its budget deficit.
