while the [non]scaling of benefits argument does have a lot of merits in theory, to show that it isn't the primary reason on practice : imagine that the 10-man team comes to town simultaneously with Amazon, then it is kind of obvious that addition of their $109K salaries would provide proportionally the same benefits as those Amazon salaries. Yet that 10-man team would still not get the same tax breaks/etc. Because the benefits are _forced_ from the government by Amazon for Amazon, and not _given_ by the government to the businesses satisfying some criteria of being beneficial for the locality.
