2. Tax should be evenly distributed
If you want jobs, don't tax jobs.
Amazon may be a large employer, but its not the only employer. Everyone should be taxed in proportion.
What they should tax is land use per sf of lot (not sf of the building).
Now people who use a lot of land, or who use the land inefficiently, pay the penalty.
It should also apply equally to everyone who uses the land from large private home owners to small bookstore and cafe owners.
I know there is property tax on the value of the property, but that is a different incentive (to build cheap). This is the incentive to use the space efficiently. So use some amount per sf of lot (say $0.5? I don't know how much that would raise).
