The new Supreme Court ruling, the end of Democracy? Should the Supreme Court be abolished?

This is a devastating blow to Democracy. Corporations and labor unions have too big of influence even without this ruling. However I fail to see how this is a republican victory when it is clear that no one wins except Oil companies, health care companies, wall street and giants like mc donalds and wal-mart. They do what they do not in the best interest of America but for the interest of profit. These are the groups that will be legislating soon.
