Cap and Trade

SO now the Environment is a big debate that is happening in this years Presidential election. The question is, who is the right person to take the job? The theory of cap and trade is one that would u the nation on a carbon diet. Which the article says is very expensive. And all that means is that the American people will have to pay a higher tax just to solve a problem that is very debatable as to if it even exists. But not only do the companies make more money in not producing as much carbon they get to give that money to other companies to invest in technology to lessen their carbon emissions. Which is not even the root of the problem. However, last I checked this nation was a democracy, and in a democracy we are a mixed economy leaning more towards capitalism. And in such the nations economy depends on competition. Strong companies need to compete. How can the companies compete if they help each other out? I smell a socialist movement. If we find "cleaner" sources im ok with that. But I want cleaner sources that are cheaper than gas. Cause if I have to buy a new car to put fuel in that is "Clean" but cost the same… I’ll be one angry individual. Especially because ill be paying the same price for something different just because its "clean"
