All enterprise builders are business-man but all businessmen are not enterprise-builders.
The difference is very subtle.
A blog writer may be an enterprise-builder but a billion dollar corporation may be a mere business.
So what is the distinction ?
The overwhelming distinction is simply this : an enterprise builder has a philosophical foundation resting on many pillars. A businessman has a sole foundation and that is the foundation of money.
Hence, the world mourns a big business collapsing or going bankrupt but passing of an enterprise builder makes us subtly poorer and hence most have no idea of the colossal loss.
