What ideological perspective is presented in the following source?"It seems equally logical to me that individuals cannot be free if they are beset...

It is not really possible to say exactly what ideological
perspective this passage comes from.  It clearly comes from a perspective that is in
favor of the welfare state and opposed to laissez-faire capitalism.  However, it is not
clear if this quote is from someone who is center-left (like an American Democrat or a
member of the English Labour Party) or from someone who is truly a
socialist.

The argument being made in this passage is that
laissez-faire capitalism actually reduces freedom instead of increasing it the way
conservatives say it does.  The author argues that a person is free when he or she does
not need to worry about losing out in capitalism competition and becoming poor.  The
main idea behind this is that unfettered capitalism is dangerous to people's freedom. 
This is clearly a leftist idea, but there is not enough here to tell us how far to the
left the writer is.
