That is what the author thinks. Not sure this is the actual solution. Outlawing Political Parties is the first step, but that is as improbable as it sounds.
I am not sure that I agree with outlawing political parties but removing the monetary influence companies have would help. Large companies take huge risks that if they pan out for the company they keep the profit. If something happens that destroys the company they get a bail out from society.
If theres no mandated political buckets, influence will have to be individual. Collusion less robust, since proof of political clubs would be illicit and migration to a new/other group trivial. If you are out of the R/D troughs now, thats the end of your political career. This is an unfortunate and forseen end-stage two-party system.
