FINANCING THE CAPITAL REQUIREMENTS 271 long way toward preventing the state from having an accumulated deficiency of any size in the future. In out- lining such a plan, it should be recognized that over a period of time, a certain per capita expenditure for penal, eleemosy- nary, and other institutions will be necessary. Although there will be variations in annual capital expenditures for these purposes, the development of such a plan should lessen the possibility of having to finance an excessive outlay in any one year or during a short period, since the plan should provide for sufficient income to meet the ordinary needs of the state for these purposes. It should not be assumed that a bond issue would neces- sarily involve a definite departure from the pay-as-you- go principle in financing capital needs other than for highways. On the contrary, the pay-as-you-go policy may be desirable in the long run, though it may not be ap- plicable to a situation such as that under consideration. Also, regardless of whether the state desires to continue on a pay-as-you-go basis or to return to it as soon as the present bond financing is completed, it does not follow that the capital needs of the state can always be met satis- factorily in the future without resort to borrowing. Rapid changes of a social and economic nature often cause an in- crease in institutional needs that cannot be foreseen. When such is the case and it is recognized that the need is a real one, strict adherence to a non-borrowing policy may only mean a postponement of the capital outlays until conditions have become almost intolerable. The present instance is a good example of the inade- quacies of financing capital improvements out of current revenues, to the exclusion of receipts from borrowing. It has been shown that on a per capita basis Missouri’s ex- penditures for institutional needs have been exceedingly low. The constitutional limitations make it impossible to borrow considerable sums for such needs, the assumption being that they will be cared for out of current revenues. The con- struction of a new governor’s mansion, which has been needed for many years, and of a needed administrative office building has also been deferred because of such limitations. There is a sharp contrast between the rapid development
