Other people answered you well, but I could sum it up as financialization doesn't help society. It puts up barriers to free trade, monopolizes businesses, adds rentier like barriers to society. A great financial system also makes it easier to get a loan, invest in things, get credit. For wealthy or fortunate people like most programmers this is all great. For poorer people it adds to the tax or drudgery and difficulty of having a good life and affording it.
