According to the passage, what is the difference between T-bills and T-bonds?
Write a precis of the following passage with a suitable title:
Most men long for wealth, Wealth, they think, brings happiness. But often, wealth brings a deal of worry without much happiness. A millionaire is a very wealthy man, of course, but his great wealth is also a great responsibility. He may have many large estates and factories. Estates and factories usually need a lot of attention. There may be disputes between the millionaire and his workers over one trouble or another. These disputes may lead to strikes and conflicts, for which the millionaire may lose a lot of money. Or some gangster may kidnap the millionaire's child and demand a huge ransom for the safe return of the child. A very rich man, therefore, in spite of his great wealth, may not have an easy life. He has many worries. These worries may be greater than the worries of a poor man.
