From this lesson, what could workers do to win higher wages and better working conditions?

become entrepreneurs
write letters to the government
destroy factory machinery
go on strike

Becoming entrepreneurs 1) doesn't guarantee anything and 2) is unrelated to the "labor" of the currently occupation. Going on strike has always been the most successful historical option throughout the history or organized labor.
