There have been Supreme Court cases arguing similar issues. Plaintiffs arguing about expanding the bundle of fundamental rights included in the constitution to include a right to education, food, shelter etc.---
These are not fundamental rights and will never be fundamental rights. Forget about the slippery slope argument ( i.e. adding the right to have a college education, wireless internet, sex, recreational drugs all the way down until the concept of "fundamental rights" becomes utterly meaningless), from a legal standpoint adding these things are impossible. Only the Supreme Court can interpret the constitution and make judgements accordingly. Congress can never infer or legislate beyond the bounds of what the text of the constitution explicitly states. And who decides what the constitution says? The Supreme Court.
So from that standpoint, you would need two thirds of both houses and 75% of all state legislatures-- or its impossible.
So, for obvious reasons, amending the constitution is pretty much impossible from a logistical standpoint. Second of all, making these kinds of amendments will force the country to become communist, destroy our standard of living and pretty much make America inhabitable.
What liberals cannot grasp is that inequality is part of the human condition. The only thing the government owes you is an equal playing field-- the rest is up to fate, your parents and your own abilities.
