This is a great article from Joan C. Williams at the Harvard Business Review. The white working class, households with a median income of $64,000, have largely been ignored by both major parties. Each party, influenced by neoliberal ideas, supported trade deals like NAFTA that shipped working class jobs overseas.
Trump, whatever you think of him and his politics, spoke to these people.
Hopefully, this will be a message to both major parties. You cannot keep ignoring the needs of the working class and expect to be successful.
