There is no "economy." Meaning that the free market does not produce anything much in the U.S.
Except for those involved in the service industries, all the production jobs especially for younger wage earners who work with their hands have been shipped to China.
If you are older and have already accumulated your wealth, your assets, then the economy is ostensibly good. Because inflation which makes gasoline, food, rental housing, car prices and house prices higher and higher, just increases the price of your already accumulated assets -- like your house or houses and cars and stocks, etc.
But for this sport to grow, the younger men, especially, have to have sufficient disposable income to buy and maintain a jet ski.
They don't have it.
Because they can barely afford to live at all.
Many I have seen have moved back home to their parents taking their young children with them.
Trump has it right when he says that the price of energy is the prime creator of inflation -- because the cost of fuel is a part of everything which is produced, including the raw materials, the manufacturing and the transportation of the goods to market.
Trump is also right that this can be relieved by "Drill baby drill!"
But inflation is not caused just by the cost of energy.
It is also caused by the Federal Treasury printing dollars which the Federal Reserve buys which has increased the U.S. National Debt to over $35 Trillion. And $1 Trilion more is added to the National Debt every 100 days.
Now the U.S. dollar is no longer supported by gold or by the working man. Rather the number of U.S. dollars continues to outpace the productivity of the U.S. working man. Only a huge cut in federal government spending, like firing 2/3s of its employees can turn the economy around now.
So in summary, our sport is not dying.
America is dying.
