Everyone knows that's the idea. But $1.2 billion is a lot of money. how long will it take to make this foregone revenue back in taxes? If there are 6000 employees, they're going to have generate $200,00 each plus interest in tax revenue before the state of Nevada breaks even. Nevada doesn't have a state income tax so it's going to have to get that money back through sales taxes, which means (assuming the top rate of 8.1% in the state) after each of the 6000 employees households has spent about $2.5 million within the state.

Don't hold your breath, in other words. Even with the most optimistic economic multipliers I don't see the state breaking even on this for about 25 years. I think they're gambling on the 'gigafactory' being the center of a manufacturing hub that attracts other businesses to the region, sorta like HP in Silicon Valley back in the day. Perhaps they'll call it 'Lithium Oasis' or something if it works out.

I'm neutral on this, and I hope it works out for them, but it's not the sure thing you suggest. Companies that get huge tax breaks sometimes crowd out other employers that were willing to do a better deal, only to up sticks and leave as soon as the tax break expires. I'm not saying Tesla will do this or that they shouldn't seek the best deal, just that it's not guaranteed to be a long-term benefit.
