As far as I can see there is always work required if you want to make money online!
Sure it is easy to create a blog with Blogger, but you need visitors to visit the blog if you are going to make money.
It is also very easy to add Google adsense to your site but again without visitors your blog will not make you any money.
Traffic to a blog is crucial!
Getting Traffic to your site will inevitably require work. This includes listing your site on submission directories for one way links. The same has to be done for the blogs RSS Feeds.
The layout of the site is also very important, whether you are trying to make money via affiliates or adsense. To optimize the site and make any form of meaningful money will require time and effort.
Content is also of the essence. Even if you only want visitors to come to your site to click google ads the content is crucial. Search engines such as Yahoo, Google etc no longer base their rankings solely on meta tags, they now have a far more refined search that picks out the most relevant sites for content relating to the visitors search query. Therefore if you want your site to be the one the visitor and the search engine selects then you need quality and unique content.
Of course you can play the numbers game and start up as many blogs as possible skirting over the various web 2.0 issues but are you going to get rich by doing that. My guess is no!
The moral to this post is that in order to create a blog that is going to bring in some extra money you are going to need to put in time and effort. There is no way round this fact. Of course as you become successful you can pay people to write articles or look for advertising etc, but I fear this is a little way down the line.
