A lot of time I do what I do and don't sit down and ponder on it. I got to thinking about how different people pay different amounts for the same thing without even knowing it!
Lets say one guy has an investment that makes 5% and another guy owes 5% on his house and has 20 years left to pay. For either of these guys if they buy a $1k piece of equipment rather than paying on the mortgage or putting it in the investment they have effectively spent a lot more than they thought. The guy with the mortgage payment just spent $2000 when he bought it. (20 yrs x 5% x $1000 = $2000). The guy with the investment suffers the same loss over the same time period. Another guy with the same mortgage who pulls the $1000 out of a 5% investment actually spends $3k for the same $1K piece of equipment in the long run because he lost $1k from the investment, paid $1K more in interest on the mortgage plus paid the $1K for the equipment. Another guy bought it for $500 used with money he made extra from selling other stuff.
I concluded that depending on how you do it you can end up paying anywhere from $500 to $3k for the same piece of equipment.
Anyone else got any babble on money thoughts or other ponderings? :D
