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.
I'm lucky to have a lot of savings. I regularly get calls and emails from Scotiabank telling me to buy mutual funds and increase my credit limit. I always figured that if someone contacts you saying they have an offer that will make you a lot of money, they're lying. CBC seems to confirm that.
If you have a notable amount in savings, investing it in some way is generally a good idea, but I agree with not trusting your bank to steer you right.
