"....while the other isn't due until some future time ..."
I am all for spending only what you can pay for, but are you against taking out a mortgage for a house to be paid over many years ?
For example, a new sewer system, if paid for immediately out of funds saved from the water rates of current users, would benefit those who who move in and have not paid for it, they get a free ride.
The expectation is that things will get better and the populace more prosperous so that the effective "bite" is less in the future years.
After the first 10 years or so of a mortgage, you could not hope to rent the same place for the cost of the payments you are making.
This discussion of the abuses of direct democracy does not involve voluntary actions. The discussion involves the imposition of the will of a small minority on a majority of individuals.
An accurate analogy would be:
but are you against your neighbors forcing you to take out a mortgage for a house to be paid over many years ?
I'm not. But I am against taking out a mortgage to pay for car repairs, groceries, and prettying up the garden.
(which is equivalent to what much of this bond money does).
