Was Bush's plan for SS private accounts a last ditch attempt to save Wall Street?

Bush tried very hard to create personal accounts for Social Security that would allow people to invest in the stock market.

Given current events, is it possible this plan was a last ditch attempt to avert or delay the current economic crisis?

It would also enable the rich to preserve their money, while the poor and middle class have their SS savings wiped out in the market. The poor and middle class have never been a particular concern of the elites.

I have a really hard time believing that all these highly connected guys didn't know what was coming well in advance.
