A movie costs $12 in a theater for 2 hrs of enjoyment. A lottery ticket costs $1 for a week of intermittent enjoyment. For certain segments of the population, a lottery ticket is a downright bargain.
Math problems are easy. Real world problems are difficult.
As an aside, it's so important that people who care enough about a social challenge like the lottery/gambling addiction are able to find the ACTUAL root cause to address. I'm not blaming the LA Times. I LOVE content like this - and not all content needs a purpose. BUT - if the purpose was supposed to be helping people who play the lottery see their folly, this probably isn't the right tack.
