Who benefits and who suffers most from a centrally planned economy?

Who benefits:

• The Central Planners -- all of those bureaucrats are employed with the purpose of creating the central planning and, as a result, their very livelihood exists only by dint of the planned economy.
• Black Market Smugglers -- Black Market Smugglers get much more traffic for needed goods if the economy cannot anticipate people's needs and this happens very commonly in planned economies.
  

Who suffers: Everyone Else

• Entrepreneurs are banned from starting new businesses that sell their own products.
• Businesses have product overflows in some categories and shortfalls in many others.
• Common people cannot buy everything that they may need or want.
