We live in a world where McDonald's is using AI to dynamically price hamburgers. Every piece of information about your life is something you might want to hide just to avoid being screwed over harder financially than you otherwise would.

You medical history will be used to avoid hiring you to keep health insurance costs down, even if it's illegal. Your gambling or alcohol addiction will be used to target you with for gambling or alcohol advertisements even if they made that illegal. Your financial status will be used to mark up prices of things you need to buy, like how airlines used to show higher prices when you connected with an iPhone.
