"Go West, young man" is a phrase, the origin of which is often credited to the American author and newspaper editor Horace Greeley, concerning America's expansion westward as related to the concept of Manifest destiny. No one has yet proven who first used this phrase in print, although 21st century analysis supports Greeley as the phrase originator.
Washington [D.C.] is not a place to live in. The rents are high, the food is bad, the dust is disgusting and the morals are deplorable. Go West, young man, go West and grow up with the country.
