"Trickle down economics" is a disparaging description of economic policies designed to enhance the overall level of prosperity in the country (e.g., a tax cut - which, of mathmatical necessity, would go mainly to high-earners). According to critics, the only way "the common man" would benefit from such a measure would be when The Rich spend their additional take-home income on services and locally-manufactured goods, vacation homes and whatnot, thereby creating employment for The Common Man.
Progressives, on the other hand, favor policies whereby The Common Man is empowered to demand more from The Rich and from Corporate America - increases in the Minimum Wage, increased unionization, greater public and quasi-public employment.
Allow me to speak for all Progressives (which is arrogant, but since you did...) and edit your remarks:
The Common Man has the right to end the exploitation of his/her labor by demanding an increase in the Minimum Wage, the right to organize and join with others to earn fair wages and benefits, and to strike for the same while petitioning the support of the public and his and her's political representatives.
That all sounds good, except for the fact that there are more comman men than common jobs, and that leaves some of those common men out in the cold.
So, you work on improving the lot of the common men with common jobs, and I will work on increasing the number of jobs and getting the rest of those common men out of the cold.
- Can we increase the number of jobs by raising taxes on the wealthy? I don't think so.
- Can we increase the number of jobs by raising the minimum wage? I don't think so.
- Can we increase the number of jobs by extending umemployment insurance? I don't think so.
- Can we increase the number of jobs by mandating 'fair' wages? I don't think so.
To increase the number of jobs available, and get those common men out of the cold, we need to induce the entities that have capital to invest that capital in an enterprise that does create new jobs. So, how do we induce entities with capital to invest to actually invest that capital in job creating enterprises within the United States of America?
- Can government mandate that entities with capital to invest, invest it here? No.
- Can government shame entities with capital to invest, into investing it here? No.
- Can government make it more profitable to invest here than anywhere else? Yes.
Obviously, the third option is the answer to more jobs in America, and more common men in out of the cold.
