Growing up, I worked in a town basically built by IBM. Big blue man, all the way. I remember a teacher asking how many of our parents worked for IBM, and it was atleast 60% of the class. When you then consider the rest, people who work in retail, food, entertainment, mechanics...they are all people who make it possible to survive, and all rely on "big business" to keep the community functioning.
I would be careful jumping on bashing the big business lot - because there is NOT a set definition and likely the people who are really out to get them are boarderline socialists, IMO.
So, for example, if you REALLY think that raising taxes on oil companies - this it is right to go after "BIG OIL" and that it surely will result in a decline in gas prices....OMG we need some education in basic economics.
