OK, lets look at company match specifically.
I was 25, making 70k/yr, company match was 0.5% per 1% up to 6% (for a total of 3%).
The mustachian would say, no matter what you shouldn't leave that on the table, you will absolutely be better off.
And then at the end of the year the company decided not to match.
I was there for 6 years and they never matched once. You don't know what the future holds, and aggressive optimism is fine, but it isn't terrible advice to focus on those things you can absolutely control, like your level of debt and how aggressively you pay it down.
Did I still contribute to my 401k? Yes. Am I better off than if I had used that money to avoid buying things with debt? That is a really hard thing to say, and the answer is probably: barely. Marginally. Not significantly I'm sure, and I might be worse off. The math doesn't capture the nuances of the actual experiences of an individual. It isn't any more wrong to dispense bad advice because mathematical models told you it was good advice than it is to dispense bad advice that will turn up a sub-optimal solution in certain scenarios.
What Dave is doing, and if I could figure out how to do it better I would, and you should too, is raise the overall financial literacy of a lot of financial idiots.
If I could figure out how to teach teenagers to manage their money properly and get them to actually listen, I'd quit my job now and do that instead.
