The under 20 crowd are larger than Gen X but are NOT larger than Baby Boomers.
Tight labor markets are inflationary. Inflation is particularly bad for those on fixed incomes. Many boomers, perhaps a majority of boomers, have not saved adequately for retirement; and the Greatest Generation is living longer and spending more on medical care than previously expected. Fears of inflation, inadequate savings, and delayed/diminished inheritances will cause many boomers to delay retirement well in to their seventies.
