During the holidays, we always find time to relax and unwind. Some people might file leaves to enjoy some quality time with the family. But, there are also professionals who never stops working and can be most profitable on holidays.

Dentists

There’s no question that dentists earn a healthy salary year-round. In 2007, the average net income for an independent private dental practitioner who owned all or part of their practice was $205,960 for a general practitioner and around $353,280 for a specialist, according to the 2008 Survey of Dental Practice.

However, while they’d probably never admit it, Halloween is undoubtedly a dentist’s favorite time of year. About 40 million trick-or-treaters celebrate Halloween each year, according to U.S. Census Bureau statistics. That means 40 million sets of teeth are exposed to the decaying, damaging effects of countless sugar-filled candy bars, chewy-gooey bubble gum, destructive jaw breakers and an array of other sweet treats.

Caterers charge anywhere from $15 to $40 a head plus a delivery cost for a Thanksgiving meal. Some extremely successful businesses cater as many as 800 meals on Thanksgiving day. Talk about some serious cash! No wonder caterers start salivating at the mere suggestion of the holiday season.

Debt Counselors

Last year, U.S. consumers spent a total of $28.5 billion on Thanksgiving and another $460 billion on Christmas expenses, according to IBISWorld. Some studies show that the average American family spends $1,500 or more each holiday season.

After taking part in this carefree, holiday spirit-induced spending spree, many of us wake up in January with serious debt hangover. Last year, 31% of credit card users were still working to pay off their holiday debt in March or later, while 13% were still carrying Christmas debt six months after the Yuletide season.

Apart from all this, it’s nice to know that are people who are working hard. There’s more at Investopedia.com.
