The 401k only works if you use it. If you don't invest, you won't have any retirement. Your example about people having nothing in a 401k because they don't invest reminds me of people that don't receive Social Security when they retire because their government job opted out of SS. Their pension is about 55 or 60% of their working income and they complain they can't live on that. Why didn't they invest the 6% the rest of us have to put into SS each month and they would be sitting on plenty to retire with.
I am not as smart as Tex but I know the 401k works for those that are smart enough to use it. You start when you are young, invest a little at a time and get a company match of up to 55% of your contribution. You stay with it, getting 10 to 15% returns plus saving 12 to 15% on your taxable income come tax season. 30 to 40 years later, you are sitting on a nice nest egg come retirement.
If you just save $100 a month between your contribution and the company match for your entire work career and get a very conservative 8% return, you will be sitting on close to 300k come retirement. That would be about $20 from your weekly check and $5 company match. People that complain they can't save $20 a week are the same people drinking Starbucks 5 days a week, driving new cars with huge car notes and watching every possible premium channel on their TV at home while they have the latest and newest I-Phone every time they come out. Most Fedex employees can save money, they just have their priorities in the wrong place.
No it doesn't work for the majority of workers that use it.
The data about 401k's shows actual workers who are putting money away in their actual 401k plans and it is not working for the vast majority of them.
Again, you are defending this thing called the 401k as if it is a person or a religion or an ideology that you are "believing in", instead of a part of the tax code meant to aid in retirement.
Either it works in reality for workers or it doesn't work.
And the data is very very clear, the 401k objectively for most American workers that are in fact using their 401k doesn't work for them at providing stable retirement income.
Now either we can discuss the factual info about the 401k and how it is actually working for Americans, or I'm done with this discussion.
I see zero benefit in continuing a discussion in which you tell me you basically believe in the 401k or you tell me you just know the 401k works if people use it or you give a theoretical example of how great the 401k works which is devoid of any data about how it works in reality for most workers.
Don't believe, don't go on theory, look at the actual data about how the 401k is actually working in the real world for actual human beings, objectively the 401k is not working for the vast majority of workers that use the 401k.
