Opinion question: are the progressive movements calls for government regulation of business justified?

This is one of those questions that you should always qualify by stating that it is a fact specific inquiry.

Depending on the facts presented, a progressive movement's calls for government regulation may be justified if the facts presented show that the call is justified.

If business is routinely defrauding citizens and ignoring tax law, then a progressive movement is right to call for regulation.

If the regulation is poorly written, then the progressive movement should be calling for better regulation and not new regulation.
