Sometimes, the advice of philosophers seems to be counter-intuitive. Like, your common sense says one thing and the philosopher says the diametric opposite of that. And also claims that the guidance of your common sense will lead to disaster. It is times like this that you feel that they inhabit a different universe where, probably, even the laws of physics do not align with what you know of the world.
Like, who could ever claim that spending conserves wealth better than saving? AND, yet, Tiru says here...
Seyarpaala seyyaa dhivariyaan selvam uyarpaala dhandrik kedum - Tirukkural
Wealth accumulated by not spending on what is needed will end up being destroyed - Loose Translation
I think some such thing has been discussed in these annals before. Not all spending is wasteful and not all saving is desirable. Let us take some truly absurd examples. If you fail to spend on doors, locks and guards, for example, can you hold your wealth safe or will you get robbed? If you confuse investments with expenditure and hoard everything in cash, will you not be allowing inflation to eat away at your wealth?
Wealth HAS to be put to use in order for it to grow, no? If you own lands, do you not have to spend money on seeds, fertilisers and labor to make productive use of it? Is keeping the land fallow, because you prefer not to spend money, the best way to safeguard your wealth?
Or, for that matter, stinting on food for your family...is THAT going to save you wealth or lead to serious expenses later - on medical complications? (Without even arguing about what is the purpose of wealth that does not even get used to feed you.) IF you refuse to spend money on your children's education, will that lead to formation of generational wealth or to the dissipation of it?
Not all spending is wasteful and not all saving is desirable. To keep the balance, without leaning too far in either direction, is the best way to safeguard wealth.
AND what is wealth if it cannot be used to make you happy? But THAT is an argument for another day.
