This particular example underscores the power of Sufficiency Economy Philosophy. If we try to follow the philosophy, then at the moment of making our purchasing decision, we have to ask ourselves at least three questions:
First, whether this home is a suitably moderate choice, given our limited resources.
Second, whether it is a reasonable thing to do to buy a large home just to show it off occasionally to our friends.
Third, whether the financing of this particular home will leave us vulnerable to adverse effects that might happen in the future.
