Write a summary of the following passage (Max  5-6 Sentences ).

Most men long for wealth. Wealth, they think, brings happiness. But often wealth brings a great deal of worry instead of much happiness. A millionaire is a very wealthy man indeed, but his great wealth is also a great responsibility. He may have large estates and factories. Estates and factories usually need a lot of attention. There may be disputes between the millionaire and his workers over on trouble or another. These disputes may lead to strike. In that case, the millionaire may lose a lot of money; or some gangsters may kidnap his child and demand thousands of pounds to return his child safe and sound . A very rich man, in spite of his great wealth, may not have an easy life.
