No, inequality is a consequence of many things and Bitcoin is unable to magically fix the reality of our existence. Bitcoin is a neutral thing. It can be used for bad things but also for good things. It won't fix the world on its own.
There used to be an inequality formerly with when it comes to opportunities to invest, I mean those times when you must have a serious amount of money before you can pursue any investment. Bitcoin removed that inequality, people of different financial levels can now invest in their own capacities.
You could invest small amounts of money in other things, this was not a new invention with the release of Bitcoin.
