I've read a lot of articles that state how N's are generally poor at handling money because money is a so-called practical matter.
However, I think it is the N who is actually better with money, and I am going to explain.
While an N will probably see something they want and be more likely to not consider price, the way they are better with money is because they look at a purchase in terms of its meaning. I think N's are less likely to go to the store and buy things because they look nice like the S. The N's purchase tends to sort out the less obvious purpose of the item, and they can better sense how they are going to use things, simply because they are more intuitive.
I even know a lot of SJ's who buy things but throw them out in a week after they're done with it. One example is a treadmill that an SJ I know bought. After she gave up interest in exercising, she would throw the treadmill out. When she decided to exercise again, she had to spend money on another treadmill. And the dance kept repeating.
The thing is, a Sensor is more likely to buy things based on their beauty, like decorating their house or something like that. A lot of things have beauty, but considerably fewer things are of actual meaning. The point is that while an Intuitive has little interest in managing their money, they are also less likely to be conspicuous spenders, since the material things they possess are normally an expression of personal identity rather than for showing off.
In terms of worldly pursuits, the Intuitive is actually the one who is more practical. In this way, the N is more in tune with the object's usefulness.
