It's far worse than that. The judiciary is able to be fired by the executive branch and that simply should not be possible.
I feel the checks on the supreme court is close. I think with 18 year ish terms to replace 1 every every 2 years consistently would work
too many people to vote for means no one knows anything about who they're voting for.
I think some appointments are fine, but they should never be soley appoint able by 1 branch/person. I3, congress should be able to put forth their own cabinet options type of thing
