People say a fool and his money are soon parted to point out that it is easy to persuade someone who is not sensible to spend their money on worthless things. That old saying that a fool and his money are soon parted applies to City financiers too, for example the 15 who entrusted City trader Hugh Lowe with their retirement cash of £20 million. Note: This expression is very variable. I have learnt from years of experience that you can never prevent a fool from parting with his money; you can only delay the process.
