@ Georgesplane- There are many government agencies that regulate and influence the food-service industry, probably more so than most industries. The USDA and FDA regulate food safety. The department of Labor and the INS influence and regulate hiring practices and work conditions. OSHA also plays a role in occupational safety and work conditions.
The SEC and IRS influence tax and financial decisions by food managers. Even the EPA and NOAA have a say over ocean farming practices, and environmental pollution associated with the food industry.
Food managers have an influence over the well-being of their customers. For this reason, the government is going to have a heavy influence over what the industry makes for personal consumption.
