I view American workers as "the center point" of my position because America is regarded as the closest thing to a purist capitalist ecomomy.
America is not even remotely close to a "pure capitalist economy" and has not been for well over 100 years.
Your argument about how workers can maintain bargaining power is seriously flawed, because--ultimately--all human labor can be replaced with technology. That is happening right now, and it is largely responsible for the historically high (and persistent) unemployment rate.
And who makes the technology? This is the same failed belief that Barack Obama has when he blames ATM's for the economy every other week 
See, Socialists/Marxists/Communists fail to comprehend that for every Bank Teller replaced by an ATM, there were literally several dozen jobs created. Someone had to design the ATM (higher paying engineer job than a Bank Teller), others had to design an assembly line for it. Others still had to set up that assembly line. Then there were tons of jobs created for the shipping of these units. Then there were tons of jobs created for the installation of these units. And finally, there have been tons of jobs created by the need to repair the units when they malfunction.
Because--with capitalism--capitalists will always opt for the lowest-cost means of production, even if it means committing a large portion of your population to endemic unemployment. That is exactly why capitalism fails.
Actually, Capitalism flourishes because it creates competition. And competition creates better products at lower prices. The problem is, we no longer have Capitalism in America and haven't for well over a 100 years. It's your philosophy of communism that is collapsing America, while you blame it on Capitalism which doesn't even exist.
It consumes itself from unfettered and unmitigated greed.
Give 'em enough rope, they say. Another metaphor goes like this:
Greedy persons are like thirsty ones amidst a sea of salt water. They drink the salt water to satisfy their thirst, but the salt water only makes them thirstier . . .
