Its not quite true, people can and do setup their own businesses and experience exceptional growth. The fastest growth in almost any country comes from the smallest entities not the largest global mega corps despite their advantages from economies of scale the country as a whole requires the smallest participants to be able to do well.
When government is passing in yet more red tape they do usually have the good sense to exclude the very smallest of business from the constant drag of government, I think its usually maybe 50 or less employees are spared requirements. That can create a problem later but at least that company is likely able to stand before being weighed down further. In some countries I've heard its very common to run a (startup) business from a car in order to constantly travel and evade the crushing force of government upon any private enterprise. People might assume that means they are not legal but the business Im referring to is just normal trade in household goods yet its opposed by the giant size of government unfortunately.
