Strongly disagree, being able to accumulate enough money to cover the bumps of life can be the difference between stringing along a middle class existence and everything working out and going broke.
An emergency fund of 10k barely covers the 8k average deductible for a family. Ignoring things like rent, food, etc, all rapidly increasing.
To have a worthwhile emergency fund is too costly for most americans. Might as well finance a car - it won't matter.
