After reviewing the material, I can report that in fact there was no statement concerning Mr. MacTavish's success or otherwise in business. The statement in the article comes from the reporter, not Mr. MacTavish and it simply says:
After operating a roofing business for 33 years, MacTavish's three sons will soon take over.
There is no lie here; the commenters suggesting that Mr. MacTavish lied to the reporter are mistaken.
