Answer:
Some arguments for disadvantages of the free-market economy:
1) Difficulty in over-coming underutilisation of inputs (this means it is difficult in a free-market to coordinate under-used resources).
2) Problems in regulation of safety (free-market firms can cheat and create harmful goods to make more profit).
3) Distribution of income is uneven (many believe the free-market rewards the rich and punishes the poor).
4) The free-market has fluctuations and is considered unstable (the free-market has a sort of business-cycle associated with it).
5) The free-market allows things like unemployment to occur (many people consider unemployment bad and preventable).
6) The free-market puts profit over humanity (some critics believe that the profit motive is more important than human well-being in the free-market).
7) Inability to produce and distribute public goods (i.e.) military protection, courts, etc.).
