The market’s self-correction will not be enough, however. Higher taxes will eventually be inevitable, since so many governments have lurched heavily into deficit. But politicians must tread carefully. Tax rises right away would be a rotten idea, since for the moment fiscal stimulus is needed. And even when governments raise the money, they should first get rid of deductions and reverse unmeritocratic measures (such as George Bush’s repeal of America’s death tax) rather than jacking up income-tax rates to punitive levels.
