No, his greatest achievement is pulling US out of the Great Recession.
Except that he didn't do it.
He even instituted policies which prolonged it, which explains why it was so grindingly slow.
- No assistance for troubled homeowners (because his programs excluded
those with less than perfect payment histories) until late into his 2nd term.
- No loan renegotiation allowed between homeowners & Fannie Mae &
Freddy Mac (the world's largest residential lenders)
- Forcing some private lenders (eg, RBS, Citizens, Standard Federal) to foreclose
upon troubled properties in lieu of renegotiation to salvage the receivable.
- Requiring borrowers to pay income tax on forgiven principal & interest,
thereby making renegotiation financially impossible for many borrowers.
Note: When refinancing a loan with this taxable event, banks require that
the borrower have sufficient cash on hand to cover the future tax liability.
I managed this, but most troubled borrowers couldn't.
Even if we put a shaved weasel in the Oval Office, we'd eventually recover
from a recession. But Obama was dangerously ignorant of real estate,
lending, borrowing, & taxation.
