These are important tools for saving for retirement, and have enabled many people to build wealth. I know people who never made a lot of money in any given year, but used these tools to save money over decades, and they now can enjoy a good retirement. Calling these things loopholes, tax avoidance, or what have you is misguided and counterproductive.

We already do not have pensions, taking away private pension options such as these would condemn many to not ever being able to be retired, or to poverty.
