Multiple. Electronics across the board will increase dramatically. Every business needs computers, phones, etc...
But the bigger impact will be the effect on small businesses. We will seen countless small businesses start closing up, because so many rely on Chinese manufacturing. Margins are already very thin and have been for a long time. That isn't a bad thing when the supply chain is a reliable machine.
Businesses closing means less money circulating in the economy. More people relying on benefits that are being cut as we speak. Prices of everything are going up and jobs will be lost and at best replaced by manufacturing jobs nobody wants. Low pay working all day in front of a blast furnace, or dying textiles till your skin is stained, inhaling fumes from textile chemicals or in a tannery.
My dad built a business starting in the 80s and only stopped recently to retire. He built a large business from scratch, mainly manufacturing in China and importing to sell in North America and Europe. Business had revenues in the 10s of millions in the 90s and 2000s, employing 100+ people. A small business that grew, contributed to the economy, brought money in from the US and Europe. Money that was used to send the children of him and his employees to college, who in turn built good careers, some even starting businesses.
If my dad instead had to go work minimum wage in a factory would that have been better for the economy? The business my dad built can still be built today. The global supply chain works. Countries export product, other countries use it to make new things, and those are sold for a profit. Yes you will have have trade deficit but that's not necessarily a bad thing. There is still a benefit to all parties.
