This issue involves complex issues of professional ethics and market competition, and different people and cultural backgrounds may have different views and practices.

In some cases, the disciples of the church may really starve to death. This may be because the market competition is fierce, and the master is unwilling to share his skills and knowledge, which leads to the apprentice being unable to get job opportunities in the market. In this case, the master may choose not to let the apprentice learn his own skills to maintain his competitive advantage.

However, in other cases, disciples will not starve to death. This is because masters can earn their income in other ways, such as through their own brands, reputations or skills. In addition, apprentices can also improve their skills and knowledge through their own efforts and experience, so as to get better job opportunities in the market.

So whether disciples will starve to death depends on the specific situation and cultural background.
