In December the US economy created 5.9 million jobs and destroyed 5.5 million. Protecting jobs isn't really an option but as long as the entrepreneurship and innovation that creates jobs runs at a faster pace than the automation that destroys them, we're good.
In 2018, the American economy passed two big milestones.
Annual GDP is now over $20 trillion.
Federal Spending is now over $4 trillion (although with current tax laws and projections, it won't be until 2022, when spending passes $5 trillion, that govt receipts will pass $4 trillion).
If you're interested in median incomes rising, you should do what you can to attract immigrants and create billionaires. Median household income and the percentage of immigrants and billionaires seem to move together. I think one reason people are threatened by immigrants and billionaires is because they represent a threat to the status quo. And that's true, of course, but the same thing can be said about progress.
“Capitalism has hundreds of parameters that you can change like the estate tax [and] the capital gains tax and it is still capitalism as long as you have market-based pricing, let people create new companies very easily and intervene where you don't see competition."
