well yes and no.  The economy has been enjoying a very sustainable steady rate of growth in the US until the last couple months.  And that have meant 8 years of nonstop bull market ... which also means guaranteed recession is on the horizon.  The more aggressive the markets rage and push us into inflation (eg wage inflation), the harder the fall will be next time around.  It is inevtiable - markets never fail to fall, they can never go up forever.
