How do spiders survive inside people's homes?

I just don't see how there is enough food inside a clean house vs. outdoors, yet so many spiders still set up shop inside attics, basements, and living spaces. How do they not only survive with such a lack of food available, but also seem to grow and thrive?

Quite simply because no house is as clean as you think it is. Spiders are carnivores, but they dont need full sized flies every day, they can live on mites, fleas, and other things that you wouldn’t normally consider viable food sources. And those things are in abundance under fridges, in tight spaces in pantrys, under sofas (particularly if the house has a pet). 

They are also very efficient animals, and can go a while without food if they require.
