Read once more the parable. There were two other characters in the plot, moreover two respectable characters, a priest and a Levite. The unpalatable fact is that these two people more nearly describe most of middle-class respectable Britain than does the Samaritan. Samaritans were despised by respectable Jews, who didn't consider there was anything "good" about them.
What the unfortunate victim needed was for a homeless, destitute asylum- seeker to pass by, not several hundred respectable people.
Jesus understood the nature of the people to whom he spoke and after 2,000 years his biting condemnation still hits home.
