There has been general inflation over time.
The selling price for my house is now ten times what I bought it for.
The other side to the coin is that America now manufactures lots of stuff that is exported all over. We now make complicated stuff that most others cannot.
The president is not actually bringing jobs home, he is assuring that there will be new jobs making what amounts to different but new stuff. The old stuff is obsolete
The affordability issue goes far beyond inflation. Offshoring our high paying jobs means that many of us can't even afford the cheaper prices.
We've not only offshored our high paying jobs, we offshored our tax base. That's money that is going into the infrastructure and military buildups of other nations instead of ours.
The government insulated us from the effects of that by borrowing and more borrowing, to the point that we're barely paying the interest on all of that money we've borrowed. I know about the fraud, but our deficits are in the trillions. Who do you think will get stuck with paying that back when our debt becomes too risky? Not us. We got ours, so we can just let our kids worry about that. That seems to be our attitude.
BTW, I've made a few major purchases this year and managed to buy American, so it can be done. All it takes is some research.
