I’m talking about encouraging people to put in use as much as possible of what they own, which means that making interaction cheaper via lowering some taxes is important to do not only for the “lower income level” people, actually it’s most important for the “rich”. That’s the candy part of encouraging economic activity, and the boot part would be taxing properties (should be done carefully, or, say, large realty companies are going to be less affected than individual owners with only their apartment\house, which would be a complete failure).
