On Tuesday's MarketFoolery, host Chris Hill, Motley Fool Rule Breakers analyst Simon Erickson, and Fool.com analyst,Mark Reeth dive into the issues plaguing McDonald's (NYSE:MCD).

With second-quarter profits down 1%, global same-store sales flat, and U.S. same-store sales down 1.5%, McDonald's appears to have some pretty fundamental problems. Mark says the company wants to improve on three areas -- staff improvements, breakfast, and mascots -- but he also believes that McDonald's has a lot of issues that it's not doing anything about. Simon sees the company appealing to the value-conscious customer because of its value offerings, but that will be a problem as it tries to upsell with higher-priced foods. 

Mark thinks McDonald's has lost relevance with consumers who are shifting from value to health. Chris thinks there's a generational shift going on and wonders how much the company can do in terms of growth even if it fixes some of its ongoing issues.
