Nonsense. NONSENSE! How do you think "it" gets up there to trickle down in the first place?
There is always a source. I believe "it" comes from driven individuals whose efforts and ingenuity, along with their willingness to take on risk, creates a good or service that others want for themselves and are willing to trade for it.
They are the source of what trickles down. They are the ones who create products and they hire people to fill the jobs that produce those products.
The better the productive "they" do, the better we all do, as it all trickles down from their initial drive and creativity.
The more you hamper them, the more that interference trickles down via lost jobs, lower wages, fewer goods and services available, etc.
It all flows from the source, whether you poison the well or keep it pure.
