Unions play a role in a thriving economy, and protect workers from the greed of corporations. We are seeing America take a turn towards a dual economy more in keeping with those of developing nations. Our middle class is disappearing. Please, please do some research on the time periods of our history with a thriving middle class - paying attention to unions, marginal tax rates, and a social contract between employers and employees. Our workers need protection now because that social contract has been fractured.
