GEN751 Even after the world has been destroyed due to the sin of greed, ten generations later, the generation of the Tower of Babel had not changed their essential values.  Using a newly invented building material called brick, they built a massive tower to create a name for themselves and challenge God.  The Midrash says that the chief value of that civilization was worldly goods, and the most important among these goods was their precious bricks.  Thus, when a person fell off the tower and died while building this seven-mile skyscraper, no one paid attention or cared.  But if one brick fell and was lost, they stopped building, sat down, and wept.  Midrash, Pirkei DeRabbi Eliezer 24.  … Today, it is the greed of companies – i.e., their desire for profit above all other considerations – that endangers lives and sometimes kills people, which is no different from the Tower of Babel generation’s practices.  AMJV 337-8
