If the ordinary American wants a greater share of the cake & bridge the divide between rich & poor, why don't they hold a national strike?
The US workforce is approximately 160 million. That is strength and power in numbers, and if they start flexing their muscles, they can bring the entire country to a halt.
Everyone should walk out from the private and public sector (you cannot fire the entire work force as no one would be left to perform the jobs) and hold one week of coordinated industrial action with a ten million persons march from San Francisco, Seattle, Chicago, Boston, Dallas and Miami all converging on Washington DC, culminating in a huge mass rally in the capital and weekend of carnival, parties and other events.
They can demand to increase the minimum wage, greater job security and rights at work as opposed to employed at will, abolish the H1-B, introduce free universal healthcare, reduce military expenditure, reform the tax system for expatriate Americans etc. If, the government does not budge, no Amtrak trains, BART subway, Greyhound buses, Police & Prison Officers, libraries, museums, schools, flights, banks, social security and even your local Safeway opening again next month for another week, costing the economy billions in the process.
The 160 million US employees have power so why don't they all unite and both demonstrate and use it?
