Was the Good Samaritan a Righteous Entrepreneur?

In reviewing the Biblical account of the Good Samaritan, it seems to me that this man was likely a man of independent means. His business provided the opportunity and the financial resources to travel. He was apparently known and trusted by the innkeeper. As he departed to resume his business trip, leaving funds for the care of the injured victim, he asked that the innkeeper keep an accounting of additional expenditures, to be repaid when the Samaritan returned. Should we not prepare to be able to provide for such events ourselves? Additional scriptural accounts suggest that if our motives are to assist God's children, we will be blessed with the means to do so.
