To some extent, yes, but because the quantity of Bitcoin is limited, at least it cannot compound ad-infinitum into the hands of the rich as is the case with fiat.
The other thing which is problematic about the current system is that because the currency is constantly losing value to inflation, governments are essentially forced to invest people's pensions into the stock market which distorts the markets in favour of certain large companies... If currency held its value, governments could just keep pensions in the form of currency and would not be compelled to interfere with the markets. Governments should not get to decide how to invest citizens' money.
A deflationary currency is good. It rewards people a little bit for staying out of the market. If you get rich, congrats, you've made it, now you have an incentive to step aside, cash out and let someone else have a go. Today, the incentive is to keep reinvesting your money even if you don't feel particularly strongly about any investment.
Today, many people invest simply because they don't want to hold cash which loses value over time. People who don't have a vision for how to improve things should not be involved in the markets at all. There should be an incentive for such people to stay out of the markets. That's what a deflationary currency would do. There needs to be a bench on the side where rich people can sit down and catch their breath before making their next investment.
