Mark Hill (Your Views, July 29) celebrated the success of his family's plumbing business, and rightly so. It was built by hard work and dedicated employees who he likewise credited. However, government did play a part. The local police protected the business from those who might want to steal their hard-earned rewards. City and state roads were used to get to customers and receive supplies. Public schools may have educated the family and employees, enabling them to operate the business successfully and no doubt educated most of their customers who can afford their services because they're literate and thus have better jobs. The fire department ensured their safety.
