Final answer:
According to Peter Singer's ethical framework, it is morally commendable to earn and donate money to charity, but it is not obligatory to maximize wealth at all costs for charitable donations. Personal choice and freedom in making economic decisions, while balanced with a moral duty to help others less fortunate, are key components of Singer's view. B) Earning more money is a morally commendable but supererogatory act.
Step-by-step explanation:
The ethical framework developed by Peter Singer, specifically in relation to earning money for charitable purposes, would likely support the notion that actively earning and donating significant amounts of money to help those in dire need is a moral obligation to a certain extent. However, Singer's approach, rooted in utilitarianism, does not explicitly mandate that one should earn as much money as possible at all costs, nor does it suggest that failing to maximize earnings for charity is an evil act. What Singer emphasizes is that we should not live opulently while others are in extreme poverty and that we should give more than what is often considered the norm in affluent societies.
Considering Singer's views on moral behavior and personal choice, it might be said that while it is good and even expected to donate to charity and help those less fortunate, one also has to consider their own life plans and personal well-being. Earning more money is encouraged as a means of increasing one's ability to aid others, but it is likely not seen as obligatory to pursue wealth to the absolute detriment of one's own life and happiness. Therefore, the conclusion would be closer to B) Earning more money is a morally commendable but supererogatory act.
