It would hit plenty of us working class schmucks too. I don't usually get to treat myself to a bottle, but it's nice for a special occasion to get actual champagne over prosecco. I guess this is the end of that.
Transport from France to Germany is a lot cheaper than from France to USA. But I don't know why Italian prosecco is so much cheaper. Same issue with bordeaux vs. (say) tuscan.
California produces many excellent sparkling wines, some of which are quite affordable. We've got a bit of a grape glut as well, so that should help with prices. European wines going to Canada sounds like a good plan as well! I'm all for anything that pries the big-money donors away from Trump but I hope this is one that won't hurt ordinary folks too much.
