Even complete domestic uniformity is possible only in very small countries.
However, tax structures seem to move in large waves as new paradigms develop – e.g. tax withholding and the VAT in the 20th century.
Tax systems tend therefore to converge, either by agreement (economic integration) or through emulation
Eventually, new significant differences arise when one country—or a group of countries—depart from the established wisdom. If successful, the experience generates a new tax reform wave.
