If, like many Christians and Moslems, we believed that those of other religions are condemned to damnation, then we would also desire to convert people. Therefore we feel no compulsion to convert others, unless they show a true desire to convert. Secondly, since sincerity is one of the criteria for conversion, we can determine that the candidate is sincere by discouraging him from converting. If he persists and does so for the love of Judaism, we accept him with open arms. The place where they sell kosher food is usually one place in a community.
All kosher food is always extensively more expensive then non-kosher food.
Dear Parent, The price of kosher products can be frustrating, and your anger is understandable. And if one is indeed in great financial difficulty, G-d takes that into account in judging the person. Another factor is the small size of the kosher market relative to the greater market. Producing in bulk brings down costs, so unkosher products can sometimes be produced for less. These inspections are stricter than government standards, and animals that don't pass inspection cause a monetary loss.
