Whose lifetime!!!!
She's right, a financial crisis like 2008 was a once in a lifetime type event. Remember, this has nothing directly to do with stock markets, a common misconception on this forum. The Fed has done a good job preventing the Depression in the US that some on here thought was inevitable. You can argue all you want about the inefficiencies of how they did it. And the end result isn't as dire as people make out. US federal debt is quite high compared to GDP but not to a level that is out of control; Canada had similar levels decades ago and got through it with higher personal taxes.
Now if Trump adds a shit load more debt by increasing spending and not raising taxes ( indeed, even reducing taxes on rich people ), his expectations of some form of trickle down solution will not occur and he'll expand the debt even more. Eventually somebody American will have to pay it down. Baby boomers are passing the buck once more on this is seems.
