Anyone claiming “deregulation” for the names sake is speaking rhetoric without knowledge. Both conservative and liberal economists agree with regulation. The most conservative of economists understand the concept of externalities. Call centers bear a clear externality. The business transaction between the telecom
Company and the caller bears a negative externality on the callee who is not a member of that transaction. Conservative economists would also agree with regulation to at least impose a cost on the transaction to reflect that externality. The problem is with policy and lobbying as you stated - write your member of congress.
To comment on a now deleted post to this comment: I’m not arguing that bad regulation doesn’t exist which can perpetuate and help continue market failures. I’m arguing that good regulation is the fix to known market failures and economists on both sides recognize that.
