Was there a particular moment between 1763 and 1783 when colonists became "americans" instead of "englishmen" or was it a process?

eh sort of both. before the revolution many people DID come to think of themselves as something other then English, although it wasn't really american it was more southern or northern. Thats also how loyalists came to be, they where people who DID still think of themselves as English. Most people didn't actually think of themselves as American till after the civil war.

Hope this helps!

based on this information, i would advocate against sweatshop labour because it exploits workers in unsafe working conditions with little pay. though sweatshops produce inexpensive goods, they harm the environment, workers, and often use unsafe materials to make consumer goods.

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
