I suppose these are great if you are never going to move from startup->business.

In the longer term, more government regulation won't be a good thing for your business.

I saw a similar article about startups in Norway sometime back.

I don't know if there is such a stark contrast; a lot of these things (especially the Startup America Initiative and the health care changes) will help small businesses. I guess if you get into a really big business, increased taxes could stunt growth, but for the most part taxes are being cut for businesses--just not the huge ones.

Are there other regulations besides taxes that you think have a negative effect here?

employment regulations. Telling you who you can and cannot fire, entanglement with the unions (France is a good example of this).
