Look for places where laws can be broken with relative impunity for whatever reason -- maybe they're small laws (like hotel regulations), maybe they're laws that address a relatively small and poor group of people (like the taxi medallion service). Find those laws, and develop a startup that can break them or exploit loopholes, and you've got your next startup of 2009, in 2020. There's probably room in environmental regulation, maybe there's a minimum amount of toxic waste you have to dump for it to be regulated, and you could create an "uber for toxic waste" where people could pick some up from a pollution-heavy plant on their way home from work and take it home to their toilet to dump in. Sky's the limit if you want a 2009-style unicorn.
