So your answer to "show me how this can work" is "trust me"? My answer is, no, I do not trust you.
Does the government have a responsiblity in how the nation's weath is distributed?
Isn't the govt ran by the wealthy? Obviously the answer is yes it is. So, this should easily explain why trickle-down economics is a flat out failure and was based on a scam.
If the gov't is run by the wealthy, it is because, we the people, elected the wealthy to office. For Democrats, corruption is a plus when running for public office. Not saying that republicans are not corrupt, just that corrupt republicans are not usually voted back into office after their faults are exposed.
Trickle down economics: character AA has money. AA has a houseful of furniture and cars in the garage. AA has investments and works to increase their income. With more money and less time AA needs someone to help with the house, another person to do odd jobs, and another person to take care of the lawn (3 part time jobs). AA doesn't have time to cook every night, so AA pays to have meals made (at a restraunt or at home). Because so many people are relying on AA, medical staff are used for regular checkups (not the emergency room, but prime paying hours). As the income of AA increases, most of the things in the house and the garage will be replaced with better items. The old things will be sold or given to charity with plenty of use (value items). Vacations will be taken contributing to the wages of hotel/lodging staffs, tourists destinations, and more restraunts.
So you have a person that contributes to tens of peoples wages in a given month. If there are enough people doing that, it makes more opportunites for people working in the service industries. The people that make gadgets have a person that will buy them. The people making the latest, greatest _____ will have someone to buy their product.
That is just the practical side of things. If they are involved with their community, or charities, there will be more contributions to those that have less.
FlipFlop:
Money is taken from those that have it in "unfair" amounts. The people that have money hide it, do not spend it in this country, and do not make purchases that indicate they have money.
The money is given to the "poor" who spend it extravagantly on name brand items, and products they would not buy otherwise. Only a superficial (appearance and status items), not value items like good furniture, appliances and quality vehicles) economy is supported with no growth. Because the "income" does not increase (standard of living increases not included because they usually match the economy), nothing different is purchased. They do not have enough money to "grow" the service industries. They cannot afford to build homes based on their increasing incomes. They do not have a lawn or do not use lawn services. They make the relatively inexpensive items in their homes or parked outside last as long as possible (when it dies, it is usually trash, no value there).
You have a choice: old and busted (the trickle up poverty) where people do as little as possible and complain their lives aren't better or the people that are always trying to improve their own lives and because of that, improve the lives of those around them. If you choose trickle up poverty, vote for the fraud in the white house, again.
