The Gallup poll cited here measures something, but probably not anything relevant to baseball's survival. Football is a once-a-week spectacle during its season, baseball is an everyday heartbeat during its. The troubled Tampa Bay Rays franchise attracted more home attendance in 2017 than did the NFL-leading Cowboys. You can use that as an alternative measure of how the sports touch people's lives. NFL football is priced out of the reach of most families even moreso than baseball, and no one is predicting the sport's imminent doom. College football is not as far out of sight financially, but again many minor league baseball teams have season attendance figures on a par with top college football. Moreover, football would have trouble selling out stadiums if games were played every day - in part because the rules of football would have to be drastically changed to enable that kind of frequency, thus decreasing the level of spectacle to that of, say, soccer (or maybe less, since futbol players don't play every day either). Baseball can coexist, as apples do with oranges. I don't suggest complacency, particularly at the college and high school levels, but high major league ticket prices are a sign of robustness, not doom. At least in the major markets, fans are waving fistfuls of dollars outbidding each other for tickets - cue the other Philip J Fry meme.
