I think this decision is just highly dependent on your situation. I am in the middle of my career here and am very healthy and financially secure enough to survive indefinitely on the 50 percent nontaxed. The retirement contribution coming as taxed money does concern me, but there are ways I can direct that into pre-tax investments that may even make it a benefit in the long run.
No offsets means I can also find another job (I was not an aviation major) and supplement my income and retirement by working.
My kids mostly adults and I really do live a very simple existence with a lot of free cash flow. Some don't due to life circumstances and I totally get that. That's why these products exist. I am glad SWAPA got them and hope that enough take advantage to make it sustainable.
