Two things about the original post.

First, although Texas doesn't have an income tax, the total assessed tax on an average person is higher in Texas than it is in Oklahoma. That is because although Texans don't pay income taxes, their other taxes that they do pay are much higher. The last time I checked property taxes down there were triple what we pay this side of the border. So just focusing in on sales tax doesn't really show the big picture, unless you are arguing you want to do away with it because it is a regressive tax, etc.

Secondly, just speaking from personal experience, although yes taxes are a consideration when a business is looking to locate somewhere honestly it is probably way down the list at around item #10 or 11. The top factors are always going to be things like 'are there enough skilled workers in the area...' and 'where is my customer located....'

Just my two cents.
