I may be a little biased here being an attorney, but that's kind of the point of a class action lawsuit though. Most people aren't going to have a strong enough case to make it worth your time or the lawyers time or the court's time but class action lawsuits are a way to hold the wrongdoers accountable. And yes lawyers make more money than the individual claimants most of the time, but if you have a case where your damages are $7.50 no lawyer will take your case and the wrongdoer will essentially be free to rip off as many people as possible for that $7.50 windfall over and over again with little no consequences since no one will sue over $7.50 worth of damages.
Now, if you have suffered a SERIOUS injury from something like a defective product where you had an actual injury that can be connected to the product (or whatever the issue is) then yes, your best bet is to find your own attorney and not be part of the class.
