US government does not have a good record. I feel like anyone that thinks it’s particularly bad now needs to read some history books. Obviously I wish it were better but this is the same group that brought you a dozen wars in the 20th century, Japanese internment, forced segregation, price controls, nuclear weapons used on civilians, and so on.
My guess is that it has more to do with reading news sources particularly aligned with one political viewpoint than the actual facts of what the government is doing.
This kind of opinion seems logical only if you don't look at history. I'm struggling to think of a government which is effective today but didn't have some horrible actions in the near past. At best I think you'll get functionally "minor" states like Switzerland or Denmark that weren't really in the powerful position the US was/is in.
And so it's much better to compare the US government's record with the record of other states, and in that comparison I think the US comes out reasonably well. Not the best, but certainly not the worst.
