What a mysterious last sentence. Are you implying that true wealth is not found in precious metals, fine wines, vintage guitars or any such commodity? Is true wealth found in true love? the kind of love that lasts a lifetime in a family.

Is true wealth found in good health and longevity?

Could true wealth be found in wisdom?

Or perhaps "undetectable in plain sight" means . . . small enough to be hidden beyond finding? Like a diamond buried in the ground.

I'll cast my vote for true love. My wife and I have shared life for 40 years now; value so precious as that can never be absconded by any intrusive .gov mal-appropriations.

Faithful love and companionship is more precious than gold, or silver, or any of those other over-rated objects of hyped-up preciosity.
