The basic duties of a national government
protect its citizens from outside interference - a military defense
protect its citizens from each other - establish and enforce a uniform criminal law
ensure that the basic needs (food, housing, education, healthcare, retirement) of all current and future citizens are met. Public tax dollars should be spent efficiently and effectively
mitigate the greed in our financial markets
One approach....
Work within the current system.
Our politicians have tried this approach through the years with little success (other than FDR's "New Deal" after the Great Depression). Obamacare simply put a band-aid on inefficient private healthcare. Student loan forgiveness did not stop the predatory lending. PPP money went to companies that didn't need it. The few that speak out against the money-changers are marginalized.
Another approach...
Tweak the Constitution.
The US Constitution is the longest-lasting national constitution by far. An estimate of the average lifespan of a national constitution (since 1789) is 17 years. Thomas Jefferson claimed that our Constitution should be rewritten every 19 years. Yet we're saddled with a document that made sense over two hundred years ago but has little relevance to today's issues.
A number of attempts at a re-written Constitution have been made by liberals, progressives, and libertarians. (1 2) However, they preserve the same basic structure of government with the same corruptible politicians. And they don't address the basic problem: taking back control of the economy from the ultra-wealthy.
The other extreme...
The moneyless society.
There has been extensive talk concerning fully cooperative, self-contained communities. An emphasis is on open-source methods for building and food production. The approach is to actually create these communities within the current economic and political systems and hope that it catches on. While this may be a version of Utopia to many, achieving critical mass is well in the future.
A middle path?
A new Constitution that explicitly takes the power away from the money-changers and politicians.
Craft a document that defines a government which focuses on upholding the rights and values of the middle class, not the needs of an economic elite. Put decision-making in the hands of industry experts backed by public initiatives and referendums. Outlaw the tools of economic slavery - interest, fractional reserve banking, and privately held central banks.
The obvious fear in using this approach is that those in power will choose to burn things down out of spite. They will crash the economy causing massive unemployment and seizing our property, businesses, and retirement savings. THIS IS ALREADY HAPPENING AND WILL GET MUCH WORSE. All we can do is have a plan in place to build a truly new economic future that works for the 99%.
