Prices going down were the only good thing in the Great D, do you think prices going up would have been better for people having very limited ressources?
People have less money in depression times so it is good that prices are lower not higher
Sure it's beneficial for consumers for prices to be lower when they go to the store and buy things, but the lower prices don't make up for the lack of consumption due to the hard economic times. Aggregate consumption falls, even though prices are lower.
China will fair well after the USD collapsed and the dust has settled
I guess it depends on how far in the future you look. They would almost certainly recover better and faster than the US, but a USD collapse would greatly hurt their economy. It would destroy a lot of US demand for their exports, and because of our close economic ties with Europe, the European financial system would also probably collapse, which would destroy their demand for Chinese exports as well. It's impossible to predict how bad it could get, but I could see a USD collapse leading to a global depression.
Its pointless to discuss in macro terms when the guy can only think in micro terms. Just write anecdotes from consumers point of view so he understands
Price of gas drops so I'll just buy double the amount and store it in my garage. Same goes for food, clothes.
I just got laid off but cars are 20% less this year so I'll just buy a car instead of worrying how I'll pay my rent or feed myself until I find work again
Or
I just made bonus this year so I'll buy a new car, take a vacation, etc.. Cause I have some extra money
