AKA "surprisingly, oligopolies are there to make money and care about their customers just enough not to pee on their faces while someone else is looking".
Interesting article, but nowhere near what Wells Fargo was doing. They had institutionalized their fake account openings. The average customer had 8 accounts (including checking, savings, credit cards, mortgages, etc.). That's obviously too many.
Unrelated to the topic at hand, but I have something like 11 accounts with Tangerine (they're free). It's convenient for budgeting for different things.
It's mostly out of laziness! I'm a big fan of "set it and forget it" approaches to life. It also helps keep track of finances and prevents splurges you can't afford. If I have $300 in my "travel" account, I'm not going to go on a $1500 trip.
