The eye of the needle was the security door/gate in the wall of Jerusalem, that was guarded and left open for night travelers. It wasn't big enough for a camel to get through, unless he was unpacked and crawled through on his knees. Think about it ;)
So, the way I take it, the admonition was NOT against getting rich; it was against getting rich by taking advantage of people without their permission (i.e., by extortion, theft or fraud instead of by trade in beneficial, wanted goods and services).
"It is truly a triumph of rhetoric over reality when people can believe that going into politics is 'public service,' but that producing food, shelter, transportation, or medical care is not." -- Thomas Sowell, PhD, Professor Emeritus, Economics, The Hoover Institution, Stanford University
Get a smaller camel? :-)
