The author makes a generalization that people today are not as concerned about eating healty as they were a decade ago and based its assumption on the selection of food that three restaurants offer and how their success changed over time. The conclusion suggested in the argument cannot be attributed as the sole cause of evidence, and there are other rational and reasonable explanations.

First of all, the argument uses the questionable assumption that people care less about their health because Heart’s Delight started including fatty cheeses in their product line. However, a reasonable amount of cheese cannot be regarded as unhealthy as long as people continue to purchase nutritive vegatables and fruit at Heart’s Delight.

Secondly, the author fails to consider other reasons for the success of House of Beef. In the argument, the author assumes that a stronger demand in beef resulted in the success of ‚house of beef’ whereas a vegetarian shop next door is not as profitable. However, the higher profitability of the beef shop might have been attributed to other factors such as a successful marketing campaign, lack of competition or generally higher margin.

In order to understand the argument better, we need additional informantion about the evidence presented in the argument. For example, it would be helpful to understand if and how the population in the town changed their shopping and eating habits over time in order to evaluate whether people increased their intake of unhealthy, fatty food. In addition, it would be helpful to understand what factors contributed to the fact that the owners of ‚House of Beef’ are millionaires.

In conclusion, the argument is based on a number of questionable assumptions and the evidence suggested in the argument may have been caused by other factors and the argument is therefore not logically convincing.
