Let’s finish with capitalism
The new system I have proposed would offer much more market than capitalism can afford. First, we will establish a permanently open labour market. Each public work post will go to the worker who offers the highest productivity at any time. Productivity could be measured by earned money, by the quality and quantity of goods produced, or by customers' evaluations of workers. A worker who offers more profits, manufactured goods, and better or cheaper production will get the job.
That is an idea. How to make such changes to bring the most possible advantages and the least possible disadvantages to society is just a technical question. I have defined a pretty good solution in my book Humanism, but it would likely be much more developed through practice. Today, a labour market almost does not exist. Once a developed labour market starts to work, it will bring higher productivity, disalienation, balance among people’s needs, harmony among the people, and benefits to society that exceed today's wildest dreams.
No economy can be more productive than one where the best available worker gets each job. Such an economy will easily become significantly more productive than the capitalist one, forcing the latter to recede.
In a good society, a human being is a central value and not capital. When capitalism ends, humanism will step in, and an unthinkably better future for humankind will begin.
