Roast me if you want, but out of all the cars I've had over all the decades. I have never changed PS fluid. The last issue I've had with a PS steering pump was a blown hose in a '67 Cougar (pump was fine). Never had a pump fail yet and I keep cars 10 years or more. Current ride is going on 18.
They are "life time" fluids. So for the life of the tranny you don't needs to change fluid.
The life of the tranny might be short because you did not change fluid, but the fluid will last the life time of the tranny. (loser)

" Simply built to last. I bought my 2013 Mazda5 Sport used in November 2013 with 6K miles on it. I drive 350 miles per day doing a delivery route. I now have 306K miles and had absolutely no problems. I replace the oil every 5K, transmission fluid 60K, brake fluid 60K, coolant 90K, PS fluid 90K, plugs 90K, and fuel induction cleaning 90K. Original engine and transmission run great. I still average 29.2 mpg making 15 stops along my 350 mile route. The car is rated at 28 mpg highway. I will buy another one if the ever gives up. "
