The practice of employing former industry executives in regulatory agencies, like Wall Streeters at the SEC or pharmaceutical execs at the FDA, raises concerns about potential conflicts of interest. Discuss this issue.
Examine the Arguments:
Proponents:

Industry experience can provide valuable insider knowledge and understanding of the regulated sector.
Former executives can be more efficient in implementing regulations due to familiarity with the industry.

Critics:

The “revolving door” can create cozy relationships between regulators and the regulated, hindering effective oversight.
Industry experience can lead to bias favoring industry interests over public safety or consumer protection.

Analyze the Evidence:
Research examples to support or refute the arguments above. Consider specific cases where industry experience in regulatory agencies has been beneficial or detrimental.
Evaluate the effectiveness of existing ethical guidelines and recusal mechanisms to address potential conflicts of interest.
What do you think? 
Do you believe the benefits of industry expertise outweigh the potential drawbacks? Why or why not?
