In my hometown there once lived
Two house-painters who competed
In mastery without a moment's rest.
One day it happened that on the top
Of the nose of one of them there was
A little bit of paint, like a fly's wing.
The other whirled his axe so as
To produce a wind, which instantly
Carried off the paint entirely,
Leaving the nose uninjured and
The face of his partner unflappable.
Later on, when the mayor heard of that,
He called the painter and said to him,
'Try and do the same thing on me.'
The painter said, 'I have been able
To trim things in that way, but the stuff
On which I have worked has been dead
For three years now. Since the death
Of my partner, I have had no material
To work upon. I've lost my former skill
Because from that time on, I have had
No one with whom I could rival, sir.'
Trusts and mergers leading to monopoly (Amazon, Walmart, etc.) are not healthy competition. They are very unhealthy because they move wealth from the people to the very rich corporate owners, managers and stockholders. Many have not learned this simple lesson and continue to flock to unhealthy competitors for their goods and services.
