The tax cut and the realignment of our tax policy for international business, including the repatriation of overseas earning, is quickly resulting in domestic investment and capital spending. There is also a willingness to support a weaker dollar and impose tariffs on competitive imports, which could stimulate more production short term.  This is a lot of stimulus at once at a time when unemployment is at a record low. This could impede the productivity growth that should be a priority. We need productive immigrants even more.
