What advantages does a class action have over a regular lawsuit?

Class actions have many advantages over conventional lawsuits:

Class actions allow people to file a claim as a group, when individually they cannot afford to do so.
Class actions create strength in numbers.
Class actions force large corporations or entities to be held accountable for wrongdoing.
Class action legislation extends the limitation period before which an individual action must be filed.
Class actions place fewer obligations on class members than conventional lawsuits.
Class actions are cost effective and increase judicial efficiency because they unite several plaintiffs under one case.
Class actions run on contingency fees. That means your lawyers receive a portion of any settlement awarded.
Class members are not required to make any payments. The more your lawyers win for you, the more they get paid. It's in their best interest to gain the best settlement possible.
