If they drop the cap, all it does is hurt those who are saving, again, how exactly is that good for the middle class?

In my personal case, I will be able to pay off my home in somewhere around 2 years.  Been saving the federal max for years, and yes, I am moderately high income, that being said, the folks I used to work with when I worked in factories, many did save something close to the max as well.  All this does is discourage that savings.
