I think SFS has done a lot for the average carpet cleaner. Remember that suppliers and trade associations have always tried to get cleaners to attend business related courses and get little interest, so a course like this is worth the price of admission. At least they're not trying to get you to purchase additional packages and long-term maintenance plans.
Steve is correct in that even with a portfolio loss many or most of our customers can still afford to buy anything they want. Terry is correct in that the major amount of investment money is sitting in people's pockets for reasons other than emotion.
If you have millions to invest, why invest now? Interest rates are being held to artificially low levels, so you won't get much return. The investment in a business or building is also risky due to the current invasive government practices. The idea behind low interest rates is to get people to buy on credit, but the people with money to loan are keeping it in their pockets and waiting for the next administration and a better return on their money.
PS: Ken, the folks at SFS are noteworthy for their lack of slime. There are plenty of bad people taking advantage of others in this industry.
