Rake on pots you don't win

[pyroponic]

Technically you are still paying rake even on the hands you don't win? Meaning if the pot is $20 in $2/4, and you contributed $10 but the othe guy wins the pot, couldn't you say you paid a rake with respect to the % of money in the pot ($0.50)?

Everyone says the guy that scoops the pot pays the $1, but I think what really happened is the hand is being raked while it's being played, and so you are both paying the rake and the person who wins the pot simply takes the remaining money. Whether you win the pot or not, you are still paying an expense of playing the hand out, meaning your EV from winning the pot is automatically less by the % of the money contributed to the pot x the total amount of rake. I think this might be interesting with regards to tax purposes.
