Some companies receive public services at reduced rates, while all others pay the full cost. Some companies are excused from paying all or a portion of their taxes due, while all others must pay the full amount imposed by law. Some companies receive grants, low-interest loans and other subsidies, while all others must fend for themselves. In the end, that's corporate welfare's greatest flaw. One role of government is to help ensure a level playing field for people and businesses.
Corporate welfare does just the opposite.
It tilts the playing field in favor of the largest or the most politically influential or most aggressive businesses.
