It's the same thing as taxes. Do you complain about taxes too? It's how poker sites are able to operate.
rake is nothing like taxes. rake is a very reasonable 4 to 5 percent most places and allows us to play these fabulous games with a low takeout and if you are good enough you can still make money while essentially then paying for the online service that provides it out of your profit. it's a nice deal really. compare it to horseracing here in the states for example where takeout is close to 20%.
taxes are a lot closer to rape really, only in a metaphorical sense of course, in that you lose 50% of your hard work to overbloated bureaucrats who then use the $ to have agencys where they can figure out ways to overregulate and make free enterprise more difficult, as if the taxation rape of 50 plus percent isn't enough. Ive heard they use some of the money for good things also, like giving to people who don't have jobs so they can continue to not have a job, or give to people with "disabilities" who are able to work, or allow a woman to continue having babies w/o coming up with an income to support them, or to need to be married to the father who would need to have an income to support them. So i suppose they do some good with those tax dollars.
Anyways, I think rake,by comparison, is generally very reasonable and a great way for online poker to remain a profitable business and provide opportunity for good poker players.
