Sorry man but you are just wrong here.

The average property has increased 30% FOR ALL OF ARLINGTON. But around the stadium it has increased 10 fold. The entire zip code has seen a rise from an avg of 60k(in Q2 2011) to 140k for Q3 of 2014(last reported). That's 2.25 times increase for the entire zip code.
As to the other thing you are simply off the mark .
The area around AAC which was done after Dallas screwed up with the Cowboys is the most high dollar acreage in the actual city.
It includes the W hotel where Lamar Odom and whichever Kardashian lived. It is a couple MILLION for those apartments.
There has been a boom of folks wanting to love there because of travel.
People like living close to where they work in many cases.Especially as traffic has gotten so bad getting to and from the suburbs.
It is the same for LA, CHI, NY. The only other really comparable traffic situations.
That high value area is 5 minutes drive from Fair Park. And the Dallas Convention Center including attached 4 star hotel is like 5 minutes WALK.
The roads are under construction ANYWAYS. Having the .5% tax increase paying for them would have cost more than it did in Arlington but you have A LOT more people thus a far larger tax base to fund it at the same per person cost... supposedly 200 per year per household. Dallas has four times as many people thus could spend 4 times as much money for the same tax increase.
Arlington is on pace to pay off their Bonds 10 years early!!!! They make 500k per year off just the naming rights.
They've seen a huge influx of revenue as people eat, buy gas and other things in Arlington for these events.
It would obviously be even more revenue for a downtown Dallas area so close to the West End, Uptown and Deep Ellum.
You are simply off base if you feel this was a good decision by Dallas, led at the time by Miller.
It was a ghastly mistake and Miller has basically had per political career canned because of it.
I made it from Frisco to Fair Park in 30 minutes last night to drop off my kid at the Chris Brown concert. Aside from rush hour, traffic is seldom an issue really. In rush hour you can't get anywhere so the only way to beat it is to live shorter distances.
