Do you think that there could be a shortage of finance for new
ventures? Should the government help to provide such finance, and if
so, how?

I assume this is a question given in a class?

Why did you ask that question and what does it matter?  I paid for an
answer which I would like to have as soon as possible.  Thanks

It was a humorous inquiry... seeing an identical question appear on GA
tends to indicate that a professor somewhere has asked it. GA policy
says it's not supposed to be used to get around one's school
assignments.

If you view the GA page at the link already provided, you'll see that
there's already one possible answer to your question available for
free. It's largely an opinion question anyways, so you may get
differing answers from other people.
