Negative seo a can of worms that has been opened

Since google and other search engines took it upon themselves to start penalizing website that have spammy links pointing to them a really huge massive can of worms has been opened and google isn't going to close that can because it benefits them so much. Why is it that the only sites that are being hit are small businesses whilst huge brand are untouched... or are replacing specialized small niche sites... the search result also known as the serps have definitely not gotten better but have actually in my opinion as a daily searcher has gotten a lot worse.. as more and more small businesses go to adwords to get business it begs the question to google motives to all of this.. after all the only guys to cash in are big websites and the search engines themselves... the search results are a lot worse and dont help benefit searchers. Negative seo has even meant that if a small website is ranking above you you are able to just blast that site with tons of low quality links and get it removed... a bit like torching a small businesses shop to get rid of the competition.. this isn't right at all.. non of this is and politicians are still not going to do a thing about all of this even though it is damaging small businesses and the economy...! Something has and needs to be done... but I doubt something will be done about all of this. Here is another view on seo that may catch your interest..Seo is a drag Honestly seo doesn't make the slightest bit of sensed anymore and is a lot of hard work for little in return.
