You get $1 million per hour indefinitely, but you have to eat a piece of broccoli first. What would you do??

You could get $1 million per hour every hour of every day of every year for 25 years and barely hit the current richest person's wealth of 214.2 billion USD. And you would almost certainly still not be the richest person since that record will almost certainly keep increasing over that time period. I'm confident stating that (unless you do something special to grow the money) the record for wealthiest person will grow so fast that $1 million per hour will never catch up because it's too linear unlike the growth of wealth.
