So spending classified as investment must be done with money not previously spent in the Snow flower Harry Potter chibi character Christmas shirt, which means that investment spending of a given amount of money can occur once and only once in that time period. Any further spending of that same money counts as consumption. Once that money is used for investment spending, however, the same money can be used for consumption spending over and over again. So investment is the spending of money being use for spending and income for the first time, and only for the first time, in the given time period.
On the other hand, Snow flower Harry Potter chibi character Christmas shirt, the money for consumption spending is not money being used for spending for the first time in the given time. Since it must be spending paid for by money already acquired as income in the current time period. But any money being used for spending must have been spent for a first time or it would never be spent at all. So the only money being used for any spending must be money introduced into total spending as investment spending. And it is interesting to note that since the money spent as investment is only able to be spent once and still count as investment spending, we can conclude that the value of the amount of actual money used for the investment spending is equal to amount of the investment spending itself.
