Digital SAT Reading and Writing Practice Question #602

In Anglo-American common law, the 'rule against perpetuities' was established to prevent property owners from controlling the disposition of their wealth for generations after their death—a concept known pejoratively as the 'dead hand.' Traditionally, the rule mandated that a trust could not exist indefinitely, thereby forcing the eventual distribution of assets to living heirs. Over the past few decades, however, several U.S. states, notably South Dakota, have abolished this rule to attract lucrative trust management businesses. The creation of 'dynasty trusts' in these jurisdictions now allows wealth to be locked in tax-advantaged accounts in perpetuity. Shortly following South Dakota's legislative shift, financial institutions in the state reported a massive, unprecedented influx of trust assets originating from out-of-state settlors (individuals creating the trusts). Based on the text, what can most reasonably be inferred about the out-of-state settlors mentioned?
