What were the two primary drawbacks to the American Industrial Revolution? too many immigrants arrived poor working conditions it was limited to the east rise of trusts and monopolies

I would say A and B. There were too many immigrants and cities were prepared for all of them. That then resulted in poor working conditions and poor living conditions.

HERE ARE SOME CONS I CAN COME UP WITH

The promise of better wages attracted migrants to cities and industrial towns that were ill-prepared to handle them. Although initial housing shortages in many areas eventually gave way to construction booms and the development of modern buildings, cramped shantytowns made up of shacks and other forms of poor-quality housing appeared first. Local sewerage and sanitation systems were overwhelmed by the sudden influx of people, and drinking water was often contaminated. People living in such close proximity, fatigued by poor working conditions, and drinking unsafe water presented ideal conditions for outbreaks of typhus, cholera, smallpox, tuberculosis, and other infectious diseases. The need to treat these and other diseases in urban areas spurred medical advances and the development of modern building codes, health laws, and urban planning in many industrialized cities. With relatively few exceptions, the world's modern environmental problems began or were greatly exacerbated by the Industrial Revolution. To fuel the factories and to sustain the output of each and every type of manufactured good, natural resources (water, trees, soil, rocks and minerals, wild and domesticated animals, etc.) were transformed, which reduced the planet's stock of valuable natural capital. The global challenges of widespread water and air pollution, reductions in biodiversity, destruction of wildlife habitat, and even global warming can be traced back to this moment in human history. The more countries industrialize in pursuit of their own wealth, the greater this ecological transformation becomes. For example, atmospheric carbon dioxide, a primary driver of global warming, existed in concentrations of 275 to 290 parts per million by volume (ppmv) before 1750 and increased to more than 400 ppmv by 2017. In addition, human beings use more than 40% of Earth's land-based net primary production, a measure of the rate at which plants convert solar energy into food and growth. As the world's human population continues to grow and more and more people strive for the material benefits promised by the Industrial Revolution, more and more of Earth's resources are appropriated for human use, leaving a dwindling stock for the plants and animals upon whose ecosystem services (clean air, clean water, etc.) the biosphere depends.
