Sadly that probably won't work any more.

Just google for "supreme court" "class action" and you will find how your rights are now really limited in this regard. E.g. in 2011 the U.S. Supreme Court ruled: "an arbitration agreement prevented consumers from pursuing a class action under state law".

There have been several anti-class-action rulings by the Supreme Court.

Honestly, I'm going to buy a nice bottle of wine the day Alito, Scalia or Thomas kick the bucket.
