Ironically, it's regulation that made them like this. Obama-era emissions rules stipulated that trucks had to get a certain fuel economy, unless they were heavy duty trucks, which did not have the same requirements. The option was to either make all trucks less capable to meet requirements, or to start selling almost every truck as a heavy duty truck. Nobody would want to buy a truck that cost just as much or more while delivering less, so everybody got jacked up mega trucks instead.

While it definitely contributed to it, the trend towards SUV/crossovers was already underway[1][2] far before with CAFE standards[3]. It's also just higher margins for the auto companies (mostly similarly priced components, but upcharge for size), so they've been pushing it everywhere. While not drastic as US, the same trend can be seen outside US even without the same laws[4].
