Was the Progressive Era a success or failure?

I think it was a success, but there was some failures. Inventions were being brought up, new laws were placed, and America started checking factories. Before investigators checked factories, they were a mess. The meat packing industry was unsanitary, and really didn't care about their workers health. The oil company was basically a monopoly because there wasn't any competition, Gail Borden invented the canning of condensation milk which before it it caused many diseases, these are just some of the many things that came out of the progressive era. The failure or the bad side of the progressive era were the political machines, which was people in the political area or owners of companies/factories running corruption.

It was definitely a success for the most part, cause if it wasn't we wouldn't be where we are politically, technologically, and economically
