I have no idea which country you are talking about - though I suspect Liberia et al probably have no programs to help small business in the starting phase. Well, they do actually IIRC, but that's funded by foreign donors as a part of development aid.
On the other hand essentially entire EU has a wide-reaching support network for starting a small business. Right now, if I had a decent idea, I could walk to my local government office responsible for the subsidies, file the forms and likely walk away with several tens of thousands of euros of start-up money.
Their criteria for acceptance are basically a background check to see if you have money problems and a series of interviews to see if you have a decent understanding what you're getting into and how your business idea works. After that, I would get support from the local small business association (which is funded by both national government and EU) in everything from securing an office with reasonable rent to how to do accounting. There are several programs ongoing on EU level right now that do exactly that, plus the national level programs.
In fact the biggest complaint from the small business owners is usually that once the initial help package is used up, the "drop" in support tends to sink small business too used to having so much assistance, and as a result they are campaigning for various extensions to the start up aid. In addition they have significant other benefits, such as those in regard to taxation, employment costs and so on.
The thing with small business though, is that criteria you put on it, which tells us exactly where YOUR problem lies. You want a "replacement income" and you want it early. Fact is, many start-ups produce no profits for a long time, mainly because they are either breaking into existing market (see: the biggest problem small business faces today referenced by me earlier) or they are developing their initial product. As such, they will obviously be much less profitable than a salary of a good engineer/techie crowd that usually visits slashdot.
Which is why starting small business is hard even with the aid. And it's not the "lack of government support" or "overbearing regulation" or other bullshit that hurts BIG business and that it really likes to whine about. It's the massive competition from incumbents in mature markets where most of the small business operates that makes it so hard to start a business, which brings us to my initial point that you attempted to deny. The problem with starting a small business today is globalization and its effect on the markets.
