Mexican plant

Mexico is locating a steel plant here in my community with a lot of taxpayer funded incentives.  In exchange, they are supposed to be hiring only Americans and provide over 300 good jobs with starting salary at $15/17 per hour.  Why would Mexico locate a plant in Texas, pay employees that kind of salary when they could get workers for a fraction of that in Mexico?  What will happen is that they will take the tax incentives, build the plant and bring in their own people.  And we, the taxpayer, will be stuck with the bill.  It has happened before here.  Decision ONe was supposed to bring in over 200 good jobs.  They never produced near that number and only paid $8/hr with crappy benefits.  When their tax incentives ran out so did Decision One.  Infact, Decision One disappeared overnight.  Then came West Communications.  Same tax incentives, same crappy pay.  Very few jobs.  When the city finally had enough and yanked their tax incentives, they closed up shop and left.  It will be the same with the Mexican plant.
