Re: "Mega Corp" proves command and control can work!
This is a point well made, and one which politicians would do well to remember. Economic growth is driven primarily by small businesses forming and becoming slightly larger small businesses; big corporations rarely grow other than by mergers once they hit a certain size.
Because of this, a country's tax and regulatory system must not act in such a way that it inhibits small businesses forming and thriving. In this matter Britain is something of a flop; such insanities as tax on account (i.e. getting businesses to pay what HMRC thinks they will owe before they actually produce the runover to owe the tax) are responsible for killing many a small business at the end of its first year, and, I dare say, forcing many owners into a phoenix-like death and resurrection of businesses annually.
Similarly the EU's demand that any company using any chemical must each demonstrate its safety and the safety of the final product is similarly a small business killer. Repeatedly demonstrating that dihydrogen monoxide is safe isn't in anyone's interest, save for big manufacturers who can absorb the cost and like this bar to new competition forming.
