Be careful with the use of the word "profit" its really "financial compensation" or gain, ie, you may race and recieved winnings of say $50, but there is no real "profit" since it cost you to race say maybe $300 in fuel, hotels, meals, tolls etc. but it would be considered "commercial" just not profitable.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
