If its so efficient why do trash companies exist?

If private companies are so efficient then why does the government exist?

Do you see why framing the question that way doesn’t help you address the actual problem? I’m guessing you don’t since you seem unwilling to consider the possibility that private ownership is not the ideal solution to every service problem. I don’t think you need more than a cursory glance at the state of the US to throw that idea out the window but things must seem pretty good to you if you’re still stuck in that mindset.
