|
| Ok I double-checked, and it looks like that graph isn't
| adjusted for inflation. Here's one that is:
|
| https://fred.stlouisfed.org/series/MEHOINUSORA672N
|
| From 2000-2023, yours shows $42,499-$88,740, but that
| shows $70,870-$88,740 in 2023 C-CPI-U Dollars.
|
| Apparently cumulative inflation has about doubled
| nationally since 2000, making the consumer price index
| (CPI) about double, so $1 in 2000 was worth the same as
| about $2 today:
|
| https://inflationdata.com/articles/2022/08/10/u-s-
| cumulative...
|
| So real inflation-adjusted wages in Oregon have risen
| about ($88,740 - $70,870)/$70,870 = 25% from 2000-2023.
|
| If household incomes had actually doubled and also kept
| up with inflation, they would be ($70,870 * 2) = $141,740
| in today's dollars. Or by your graph, year 2000 wages
| that doubled and also kept up with inflation (so two
| doublings) would be ($42,499 * 2 * 2) = $169,996.
|
| Admittedly, I don't know where the $28,256 discrepancy
| comes from, so expected wages would probably be somewhere
| between $141,740 and $169,996. Maybe someone more studied
| in economics can tell us.
|
| From Jan 2000 to Jan 2023 and not adjusting for
| inflation, housing prices in Oregon have risen from
| $102,749 to $338,927:
|
| https://fred.stlouisfed.org/series/POXRMTNSA
|
| So a $100,000 home in 2000 would cost $200,000 by
| inflation and $250,000 if housing prices matched the 25%
| wage increase. But they cost $338,927, so are about 1.36
| times more expensive than expected, even accounting for
| higher wages.
|
| After writing this out, I question what a wage increase
| means if housing prices just match it. Is it really a
| raise if it's eaten up by rising housing costs?
|
| Had people invested in things besides housing bubbles,
| say medical breakthroughs or renewable energy, then
| today's housing costs vs inflationary costs would be
| $338,927/$200,000 = 1.69. So homes today are 69% more
| expensive/overengineered than in 2000.
|
| To me, this doesn't represent supply and demand. It shows
| that people have put their wage gains into more expensive
| homes, which reduced the supply of building materials and
| raised housing costs for everyone else. It also shows
| that a larger segment of the population today isn't
| working, because our economy has been moving from
| manufacturing to finance. Meaning that young working
| people are carrying a higher load to support the
| retirements of older people who have invested in real
| estate, mostly through private equity firms.
|
| You bring up a good point about aging and sick trees
| though. Most in our neighborhood were cut down due to
| neglect and disease. The 2008 housing bubble crash left
| lots empty for a year or two and the banks didn't bother
| paying the water bill, so the trees died. We've also had
