Answer: Increasing the GDP
Generally speaking, each $100K of GDP represents one job position. If GDP is at $14 trillion, then we have approximately 140 million workers.
If you wish to have 150 million workers; simple...just increase the GDP to $15 trillion.
Ten million additional workers equals more tax income at all government levels. If the political idiots can stop their out-of-control spending, more tax income can help balance budgets and pay off debt.
One caveat might be that if 5 million of each additional 10 million new workers earn lower wages, and therefore pay little if any taxes, this won't help government deficits and debt...might even make it worse.
GDP is basically the total output of goods and services. What will increase GDP...more demand on goods and services. Where can this demand be found...from domestic and foreign consumption.
Today domestic consumption is about 60% of GDP and for the near term for myriad reasons appears to be somewhat static. Therefore, how can we grow foreign consumption...which is exports? I suspect this is the answer to about 90% of our economic problems and will remain the solution until Americans can contribute by increasing domestic consumption.
To expand exports the US needs to provide something that no one else provides, and/or, the US must be able to compete on price and quality with foreign industry.
In terms of producing proprietary or unique US goods and services, the US has many options but foreign manufacturers are competing more every day for this market. In terms of competing with foreign manufacturers on price and quality, with the relatively high cost of doing business in the US, the US is at an obvious disadvantage.
If the US can keep inflation at zero for 20 years, while foreign nations realize 100%+ inflation during the same 20 years, at some point the US can better compete on price and quality. I suspect, however, that foreign inflation will rise 100% while US inflation will rise 40-50% meaning any gains will take many decades. And, it seems unlikely that we will voluntarily reduce our costs to be more in line with foreign costs.
So...in summary...although raising GDP is a solution to so many economic factors, if the US can't increase domestic demand, and if the US cannot easily increase foreign demand, thereby not being able to significantly increase GDP, and subsequently not being able to create more jobs, where does this leave us...what are the remaining options...
