Union's? Why are they here in 2007.?

What is the purpose of a union, other than to spread greed. There are no sweat shops, no unfair workshop practices, and no forced labor in our country today. Those were the reasons that unions were established. Unions are only about greed in this day and age. Why do unions only try to involve themselves in huge corporations (think GM) which have the potential to fatten their wallets, and not involve themselves in small companys whose employee's could actually use a little help. GM, UPS, and others would offer very competitive wages and benefits packages without the unions, but the unions have convinced the workers that they should get more because the company makes so much money. It is none of a workers business how much money a company makes. If you don't like how much money your company pays, look for another job or better your education. It is not a companys responsibility to finance your shortcomings. Vote republican and TAKE RESPONSIBILITY FOR YOURSELF.
