I wouldn’t go as far as “arbitration sucks and should be done away with”. There are times when two parties might decide it makes sense to arbitrate. It can take years to get a court date in some places, and you never know who you might end up with as a judge and how well they understand your industry. This is usually the “two corporate entities of roughly equal size” situation.
What sucks is the use of arbitration in consumer contracts as a tool to avoid class action lawsuits.
