Can Bedroom Communities Support Themselves?

Since most of the property tax reform proposals seem to be centered on reducing or eliminating property tax on residential properties, we ask the following: How will a bedroom community support itself if most of its tax base goes away?

Conversely, if local governments can only receive property tax from commercial or high density residential (apartments) after the tax changes are made, will this cause a sudden and drastic position switch for some local governments, which will now want to encourage commercial development to drive tax revenues?
