Good post sparklebright
the only 'loosely' common goal is we do this to earn a living ( i feel fairly confident that no-one would call it a vocation/dream job - thats not to say it isn't a great job with regards to time/money
)
the same could have been said of my old engineering trade there were people working for themselves in a garden shed
right upto companies like British Aerospace.
all make components but with different equipment all professional in their way, it may simply come down to
oppertunities and the skills of the owners on how the biz developes, and some are more than happy just
earning what they need without creating an empire
