Hello,
I think I am pretty good at understanding English considering it is not my native language. But there are a lot of phrases (and idioms?) that I am not familiar with in this poem, so I am having trouble understanding the meaning of it:

Eagles Become Vultures

in new day dreams a promise gives way
to a star struck death and a gold disease
a hollywood end for a once great man
who found death on his knees
cashed in
crashed and burned
soar
our eagles become our vultures


What is a "star struck death"? And a "gold disease"? What does it mean that a "promise gives way" to these things? Also, I thought a "hollywood end" was a kind of sappy, unrealistically happy ending to a story, but it doesn't really sound like it is here, since he was "a once great man who found death on his knees" (nothing happy about dying). What does he mean with a "hollywood end" here?

I have a hunch from looking at the title that the gist of the poem is something good turning into something bad... but I would love to get some help in understanding its contents better! How would the English experts on this forum interpret this poem?
