Vanderbilt, Morgan, others owned railroads in 19th C. Gold backed bonds were issued by Rothschilds' banks. James Hill brought in Chinese labor to work West lines. 8 wealthiest families making big money whether railroads did well or not. Until TR became President and halted monopolies. Some families lost wealth Vanderbilt, Rockefeller, others. Was there a power struggle or did people get too greedy? Is Soros tied to railroad money?
