I guess what I really meant was to be to set yourself up as a fulltime business it takes alot of money, I guess you can do it "hardcore" and nstart by making camping money, but thats a long long road and one wrong investment along the way will take you back to square one
I wouldnt say I operated a full time business but I do earn thousands of USD per year through content creation and I have never invested a single penny of rl money in sl. A friend purchased my first months membership as a gift and I have allways earnt enough to cover all expenses and to ultimately build a successful business. I had no 3D building skills and very limited graphic skills when i started, but through hard work and practice I am now skilled at both. So I think as long as you are prepared to put in the effort you can create a successful and ultimately 'fulltime' business in sl without investing any rl money, it just takes time.
I think your statement is true of players who want a very profitable business after 2 months of playing, the only way to acheive this in the vast majority of cases is to invest rl money. If your in it for the long run then no investment or rl money is necesary, or at least it wasnt before they did away with dwell, first land and reduced the stipend. It must be allot harder new players with a premium account to be self sufficient these days although not impossible.
