Few people made more then five hundred dollars a year, a top man in labor like a train engineer could earn up to four dollars a day about thirteen hundred dollars a year, this was some top wages. So my math was based on average wages. Today average wages are in the forty to fifty thousand dollar range, higher then average for skilled Workman. Unfortunately we can’t do a one to one a dollar in 1860 was worth so many dollars today. Land was cheaper some commodities were higher. Your figure of nine hundred dollars would be any where from nine months for a skilled labor man to almost two years for low skilled or unskilled labor.
