I wish we were <insert obligatory adjective here> enough to eat "all" organic and shop at Whole Foods. 
Snooty? Wealthy? Tolerant? Trendy?
I keed, I keed. 
Yeah, I hate to say it but organic is much harder as an economically viable option once your kids start eating like adults. I might have been able to do organic when they were smaller, but not now. The only thing I try to do organic is dairy products. I can't afford anything else!
One thing people may be able to do is stick to things that less likely to be sprayed. There are not guarantee of course, but there are choices you can do to minimize exposure. This not addressing the soil consern, but if pestiside and fungicide exposure is what you worried about, try this:
Instead of peaches and apples, try more figs, blueberries, maybe pears, persimmons, raspberries/blackberries and nuts. Or if you do buy other more commercial fruit, try peeling them first.
Veggies maybe a little more difficult, but getting green and tomatoes at the local famers market always good.
Try more root veggies from the store and winter squashes. Others may have better suggestion...
