Is change good?

It has been said.. "change is good" the word change has been used often in this primary election. There has been a very vague "change" being peddled and has excited many people. This got me thinking is change good? I have concluded, not, at least not in all instances. If something "changes" from a healthy state to an unhealthy one is this good? of course not. It is only good when it goes from bad to better, or gahstly to a good state. It is possible (heaven forbid) that change goes from bad to worse, or good to bad.
