Tennis is so expensive in your part of the country! It really does cut out participation in the sport for a large sector of people, which is opposite of the mission of the USTA. In contrast, I pay $160 a month for a family membership to our nearby country club, which includes unlimited use of the 7 indoor courts, indoor basketball and racquetball, indoor pool and sauna, weight and cardio rooms, and fitness classes. If I paid more, I could also add on unlimited golf.
Not long ago, the USTA took over a facility in my city that used to be $90 a month for an individual membership with unlimited court time. They got rid of the monthly unlimited membership, and went to New York City level hourly pricing. People left in droves, and the facility was empty for weeks. That forced them to drop the hourly court fee dramatically, and the people are coming back now. So, yay capitalism... the consumer decides!
