Read the following passage about urban infrastructure in Bolivia:
For decades, the geographical division of La Paz and El Alto in Bolivia mirrored deep socioeconomic divides. While the wealthy resided in the lower valleys, the marginalized indigenous majority lived on the high-altitude plateau of El Alto, navigating hours of congested, polluting minibus traffic to reach the city center. The introduction of "Mi Teleférico"—the world's highest cable car network—dramatically transformed this landscape. Beyond being a model of clean energy, this aerial transit system acts as a social equalizer. By soaring above the dramatic topography, it physically and metaphorically bridges the gap between disparate economic classes. Critics initially argued that the investment was a costly vanity project that would disrupt historic neighborhoods. However, the system's daily operations have silenced detractors, demonstrating that infrastructure can foster dignity and equity. As commuters gaze down at the unified metropolis, the cable cars serve as a testament to the power of inclusive urban design in reclaiming the public sphere for all citizens.
