Why can't America be back to the way it was back in like 2004?

Why can't we revert back to the days in America when there were no iPhones, when yes there was Social Media, but more like MySpace, and FunnyJunk, but, when there was no social media like there's now, when restaurants like Fuddruckers existed and were crowded, more people were traveling to the Caribbean in airports for Spring Break, when kids took field trips and took school more seriously, when Americans were happier, when people were still watching movies by actually going to the movies, when T.V. Channels like Noggin, WON Network, Kids WB, and Cartoon Cartoons were airing on TV, whrn kids were outside more, when DJs came to schools and when kids took hayrides during the fall of the year, when the Sky was brighter, when the roads were more crowded, and life was more like a dream, when there were more animals in the environment, when the sunsets were prettier, when the economy was better, when there was no social media, when news stories did not come and go historically, when there were bigger School gymnasiums, when there was no Internet on your iPhones, when parents took carpooling more seriously with their kids going home from school days at 3 PM, when less people were swearing, when people believed in God more, when the song "God Bless the USA" was more popular, when George W. Bush was President, when kids took field trips to environmental science museums from schools, etc?

"when George W. Bush was President"
No.

Because black lives matter movement ruined it.

Even women's breasts were bigger back then.

We have a Fuddruckers in Emeryville, CA. [See source.] Sorry about where you live.

As Thomas Wolfe, American novelist, put it, "You can't ever go home again." It means you can't go back in time, even though you can go back to the same location physically. It may not have changed, but you have.
