The government has also cooperated in some industries. The most familiar example in this respect is the ship subsidy, whereby the government for a nominal economic service pays to shipowners stated sums of money in order to encourage shipbuilding and ship operations. Irrigation is another example. Here the government builds storage basins from which it supplies water to farmers in the near-by regions. In other words, the government cooperates in production. Obviously, grave dangers lurk in government cooperation, for to open the government purse to the hands of private individuals on the pretense of public welfare, is a temptation sometimes difficult to resist.
