No, because the two have very little relationship with each other. For instance, Indianapolis has constantly been derided as a 'bad' and unsatisfying race, but it is still among the highest watched races because of the significance of the venue and perceived importance. The correlation between quality and popularity, if it exists at all, is tenuous. Commercially speaking, the sport needs new breakout stars, personalities, and cultural significance. I'm no expert on how to attain those things, but a sustained rivalry or two would certainly heat things up.
I do believe that NASCAR and the RTA should strive to achieve greater parity. You can only do that so much in genuine races at difficult tracks, because frankly Kevin Harvick, Kyle Busch, Kyle Larson etc. are just flat out superior drivers to the guys who run 15th. However, the top teams have significant engineering advantages, and I support efforts to limit those to give more teams and more drivers the opportunity to excel.
One problem is that previously they manufactured an appearance of parity, largely through on-track officiating rules that gifted teams track position and laps back, and these were all built around what occurs when the yellow flag is thrown. Now with fewer cautions, the actual performance difference is more evident. I'm not that concerned with whether there are 5 cars or 15 cars capable of winning a race. My foremost concern is that I want an honest race, not one directed by the whims of the control tower. But it would likely be in NASCAR's best interest if they could even it out more than where it stands now.
