There are two types of individual producers in any society. There are those who work for pay and those who work for profit. Those who work for profit instinctively seek to lower their costs by paying those who work for pay as little as possible. Those who work for pay instinctively seek higher pay. This dynamic will work itself out in a free market.
In the case of manufacturing of cars and clothing and electronic products the companies tasked with making a profit went overseas to find cheap labor and they did. For industries like construction and the hospitality industry and farming the profiteers hired illegals and new immigrants to cut costs on labor. These trends meant either no jobs or lower paying jobs for American citizens in industries providing semi or low skilled employment, which makes up the majority of available jobs, so the overall standard of living was reduced. In the past Republicans traditionally supported the profiteers and democrats supported the workers, or so they would have you believe.
In reality both parties have always supported the profiteers. Profiteers are capitalists who operate under the paradigm of survival of the fittest. It has been in their best interest to go global and avoid the costly American labor market. It has been essential for the prosperity of these globalist companies to control our government and other governments of the world. They have organized under several organizations like the world bank but the most powerful is the World Economic Forum. Their agenda is to recruit and control governments and they've been wildly successful. Trump scorned them as he had this absurd idea that he should consider the welfare of American citizens first over the welfare of global profiteers. So Trump was replaced by Biden. Now they're back on track.
We are not being governed by our federal government. We are being ruled by economic cabals at the highest levels and have been since the Carnegie, Ford, Rockefeller and similar endowment trusts have placed their puppets in office. The end goal is profit and wealth for the top 1% and anything is on the table if it accomplishes that purpose.
