Not only is college not for everybody, but college is no guarantee of financial success.

No. But money isn't everything. Higher education does many things for a person beside the career path, and leaving them mostly broke.

My plumber is better off than I am, and I have two degrees.

No, it can be helpful but it is not necessary. Plumbers, Mechanics, Electricians, Welders, et al, can make very good money, and can do so with out putting on hundreds of thousands of dollars in debt.

I think the critical point is skill level regardless of having or not having a degree.

Not necessary, but definitely helpful.

Banks and/or investors won't have much confidence in a person who didn't graduate college. Not having a degree doesn't mean you won't succeed, but it will very likely be more of a struggle.

No. I say no because the degree, itself, isn't the deciding factor. The person with or without the degree can be financially successful or not.

No, but it can be required for certain careers, if that's what one dreams of doing.

No. Not really.

It is not necessary, but it does make a difference. It really depends on the degree as well. A English degree doesn't usually make as much as a Physics degree. If you can get a degree it is usually well worth the time.

it helps but it's not necessary

When l was in my 20's it was another option. I'm not sure anymore. I haven't delt with that since then.

Depends on what field you're wanting to get in.
Generally, no.

In my opinion, I do not think that it is necessary. I've lived most of my life working hard jobs and getting certifications and licenses. This has lead me to be in a state of financial independence with only minimal debt and a great job to help prepare for retirement.
