Do Christian Business Owners Have a Moral Responsibility to Provide a Livable Wage?

Questions about whether Christian business owners should provide a livable wage, whether doing a corporate sponsorship that promotes one’s business contradicts Matthew 6:3, and whether the parable of the rich fool refutes America’s approach to retirement.   Do Christian business owners have a moral responsibility to provide a livable wage? Would doing a corporate sponsorship with an organization we have been working with and financially supporting contradict Jesus’ words in Matthew 6:3 about giving in secret since part of the motivation would be to promote our business? Is the parable of the rich fool in Luke 12:13–21 a direct refutation of America’s approach to retirement?
