What companies are

YES.

Absolutely. Many companies are created for the pure pursuit of money. Many are not. (what
could you do if you were rich?)

It's like saying that all political parties are created with the goal of pure power and they
don't care about anything else but achieving that power. That's obviously very silly.

Corporation is just a legal category for company. A legal entity that shields it's owners from
certain amount of liability.. ie: if you business fails they won't take your house. This sort
of thing allows companies to take more aggressive risks, like starting a new restaurant at the
edge of town.

If you look at the charter of many businesses they are created for a goal. Maybe it's getting
into space, build a better bicycle, or a new sprocket or whatever. This sort of thing is all
over the map. It's better then being a wage slave for your entire life.

Don't confuse 'corporations' with the sort of publicly held corporations that you'd find on
the stock market. Most of those guys are mostly publicly owned and the board of directors have
a pure profit motivation. They control most of the capitol, but (at least in the USA) the vast
majority of people work for (and most work gets done by) much smaller businesses. 

Small and medium businesses are the true backbone to our economy. Hell the entire stock market
isn't really all that relevant to the economy anyways.. although people pretend it is. (I
think it's due to the fact the stock market is so heavily controlled and everything is
accounted for so on a daily basis so it's easy to make pretty graphs to point at on the news
at night and on newspapers)
