I agree that a lot of the price increases we are seeing now are temporary due to supply shortages coupled with increased demand. This should only last a year or so depending on the industry.
However, we are also seeing quite a bit of money printing with, at my count, three $1.8T relief bills/budgets. Couple that excess money along with labor shortages (partially government induced via generous unemployment benefits, and partially due to reluctance to re-join the workforce due to COVID) and we will likely see wage increases. That's the real scary part since while commodity prices will come down once supply chains are back to normal, wages tend to be sticky and do not generally come down.
So ... inflation is a worry.
I do agree that there are bargains to be had in the stock market right now - and probably in beaten down real estate areas like New York. Both investments are inflation hedges.
Personally I think the disincentive to work due to the unemployment benefits is a bit overblown. But the extra government spending does mean more debt taken on.
As for higher wages, it means your fast food is going to cost more, but ultimately I think it's a good thing for the overall economy. As money has moved to the top earners, that starts to strangle the economy. If 1000 people who are lower middle class or poor have en extra $1000, they will spend it in the economy where it will spread around. Money spent in the economy has a multiplying effect as it gets passed from person to person. It also generates income taxes every time it's spent. If 1 rich person gets another $1 million, they will likely rathole it somewhere and very little of it will be circulated.
It takes longer to get back to investors, but ultimately it's better for the overall economy. The money going into the economy at the bottom does end up working its way up the tree eventually.
The guy who created the GDP measure was adamantly against including the financial markets in the measure, but they got added in anyway. His argument was the financial markets are not part of the real economy and I agree with him.
If we factored the financial markets out of the GDP for each country the US would drop significantly. The tech sector in the US is still generating real wealth, and there are some other companies here and there creating real wealth too, but too much of the US economy is built around moving money around without actually creating anything of value.
We need financial markets and banks and all that goes with it, but we're fooling ourselves calling it part of the real economy. The real economy needs to be revitalized. Politicians call it Main Street over of Wall Street, but slogans aside, it is something real we need to rebuild.
It may not mean that the financial markets will be as robust for a while, but it will vastly help the long term health of both the real economy and the financial markets if we bite the bullet and do the work we need to do.
The infrastructure investment is one area that we need to do, but we also need to boost education in the right subjects. The US has some top universities, but we're letting people come here on student visas to get degrees and then forcing them to leave the country, even if they want to stay. We're also doing a poor job of educating people for the industries that need them.
Personally I think we should identify which areas need more graduates and allow people on education visas to convert those to green cards if they choose to use their education here on graduation plus subsidize the education of any American who can get into those programs, regardless of the ability to pay.
Short term it's an expense, but long term it will pay off for decades. The US did it before with WW II vets. Anyone who fought int he war who wanted a college degree could get one. It resulted in a generation moving into the middle class. My father was in that generation. He had been in college before the war, but lamented he didn't get a PhD in Mechanical Engineering on the government dime instead of finishing his photography degree.
He said that in his father's generation we had a lot of intelligent people working at technicians in industry because they couldn't afford a college degree. Most of their kids got engineering or science degrees and built the infrastructure we built in the 50s through the 70s.
It had the effect of making the US more of a white collar country, but those jobs also tend to pay more than blue collar jobs. We now have a shortage of workers in some white collar jobs that ends up sending jobs overseas.
Back in the 90s I worked on a cordless phone project (land lines) for a company that thought they were going to revolutionize land lines. The project released one product, but version 2 was canceled before they built anything. They were teamed up with a company in Singapore to make the phone part because the knowledge of how to make a cordless land line was completely gone in the US.
Today it's antique technology, but it was center of the phone market then. There is even less need now for land line expertise, but there are many other areas where there has been a brain drain because the US doesn't have enough engineers to work in that area. The US was the world leader in designing and making quite a few products and today the US neither designs or makes that product at all.
As an investor, some of these things may not be great for me short term, but long term I think they are great for both my investments as well as the overall economy.
