We can do it (!/?)

In this article Dave Trott talks about the famous US "can do" attitude and compares it unfavourably to the UK attitude.

In New York, everything I got in trouble for in the UK was just what they wanted me to do.
Also, because America is a younger country it has a clean slate.
This gives it a ‘can do’ attitude.
If it’s a great idea let’s go for it.
As an older country, the UK has a ‘can’t do’ attitude.
This idea’s never been done before.
There must be a reason why no one’s done it.
So we’d better not take a chance.
Also I loved the anti-elitism of America.

I present the case for the defence...
