In the foregoing pages we have been considering a law which would from the beginning of its operation take _all_ the future increments of land value. There is, however, no likelihood that any such measure will soon be enacted in any country, least of all, in the United States. What we shall probably see is the spread of legislation designed to take a part, and a gradual growing part, of value increases, after the example of Germany and Great Britain. Let us glance at the laws in force in these two countries. _The German and British Increment Taxes_ The first increment tax (Werthzuwachssteuer) was established in the year 1898 in the German colony of Kiautschou, China. In 1904 the principle of the tax was adopted by Frankfort-am-Main, and in 1905 by Cologne. By April, 1910, it had already been enacted in 457 cities and towns of Germany, some twenty of which had a population of more than 100,000 each, in 652 communes, several districts, one principality, and one grand duchy. In 1911 it was inserted in the imperial fiscal system, and thus extended over the whole German Empire. While these laws are all alike in certain essentials, they vary greatly in details. They agree in taking only a per cent. of the value increases, and in imposing a higher rate on the more rapid increases. The rates of the imperial law vary from ten per cent. on increases of ten per cent. or less to thirty per cent. on increases of 290 per cent. or over. In Dortmund the scale progresses from one to 12-1/2 per cent. Inasmuch as the highest rate in the imperial law is 30 per cent., and in any municipal law (Cologne and Frankfort) 25 per cent.; inasmuch as all the laws allow deductions from the tax to cover the interest that was not obtained while the land was unproductive; and inasmuch as only those increases are taxed which are measured from the value that the land had when it came into the possession of the present owner,--it is clear that landowners are not obliged to undergo any positive loss, and that they are permitted to retain the lion's share of the "unearned increment."[96]
