True, but I don't think the US government can force the people to change. It can be taught as a school prerequisite starting in primary school, and continued through HS and college. But to have millions of workers to all of the sudden switch from one system to the next would create a lot of problems in the construction business and all the trades. For example, plumbers, carpenters, electricians, bricklayers, and so on have learned our measuring system from childhood for generations already. If you already know enough about these trades, you could understand how difficult it would be for a craftsman to change from one system to another in a short period of time.
A lot of hand tools, including powered ones, are market in inches and fractions of inches, and the lumber cuts are done in foot/inch/fractions of inches. Wrench and socket sets often include metric and US customary numbers (I have both mechanic tools, and switch back and forth).
Like it or not, the first sentence in the article below says it all:
In a metric world, why does the U.S. choose to be different?
