it's nothing but a positive aside from the fact it's wholly negative
by deceasing the amount of extra money you have to spend on things, you spend less money on things. those that suffer the most would be those with the highest prices, so big box stores like walmart and big online retailers like amazon will be alright, but then there is less leftovers for the rest.
amazon already helped small businesses. you could buy from small businesses through amazon. i really don't see how this is positive in any light, other than perhaps, increased government revenue
