Prepping not an option? Nobody says you have to have a fully-equipped top of the line bug out bag tomorrow. You can do PLENTY to prep, even if you just worked at McDonalds. That isn't an excuse.
Backpack - WalMart $12
Decent Knife - WalMart $20 (sure, there are better, and there are cheaper, but spend at least this much)
Metal Water Bottles - I picked mine up at Goodwill for $1.50 each (these have loops on the top, so my dollar store carabiners clip them to my pack to hold them in.
(3) Cans of soup/stew $1 each
Rain Poncho - $1 at a dollar store (get a couple, or spend about $5 for a better poncho)
First Aid Kit - $10 ready made, or you can make your own, better kit, for about the same at a dollar store
Spare Socks - $1 at a dollar store
So, $50, and you've got a decent bug out bag. Tell me again how you can't prep now?
Sure, this is a pretty basic kit, but it's a start, and you can keep adding to it over time, or even build this up slowly. Having this kit is the FIRST thing any prepper does anyhow, even those of us with good bug in locations. Just having this, will make you that much more prepared for anything.
