To put it simply, class action lawsuits have never been a constitutional right in the US.
In fact, in the US the notion of class action lawsuits and the rules around them were completely imported into US law (in a very weird way) by the judiciary. Even then they were skeptical.
Wikipedia actually has a reasonable history of what happened here in the US (or at least, it is similar to what i learned in law school).
You aren't actually contracting away any constitutional rights here, which is one reason why they allow it (though you can actually contract away constitutional rights in some cases)
Even the binding arbitration part is allowed, as per the Federal Arbitration Act (which has been upheld several times).
You can appeal the arbitration, just not on most substantive grounds (which sucks, but c'est la vie).
