Running a non-megacorp business and surviving without a job has not been made easier at all since the 50-60s. It's actually harder than ever as a result of government intervention and wasteful resource consumption for very little benefit to society. It makes you wonder who the government has been busy serving all of those years.
(Hint: the kind of business who wouldn't think twice about running a sweatshop via trade deals that never seem to involve clauses to require following the laws of the parent country) .
Try staring a business in a market with large established players. You'll find that you cannot do many of the things they themselves did to get started -- they have erected legislative barriers preventing replication.
Easy -- just write "think of the children" legislation demanding egregious safety, accounting and legal overhead, trivial to bear at scale, but lethal to new entrants...
