Doesn't this have an inherent disincentive to new people joining and using the network? Sorta like the poor stay poor, the rich get rich?

The inflation rate and actual utility of the currency are important factors too - if most of the currency is already distributed and the inflation is low (thus block rewards are low), the richer don't get much richer. If the utility is high, redistribution occurs more naturally as well.
Perhaps the inflation is not low but there are other distribution mechanisms that distribute currency based on utility in a higher rate than block rewards (for example on steem, of all newly minted coins in a block ~5% goes to the block creator, ~65% goes to content creators, ~6% to commenters, ~17% to curators and 7% as interest to those that have commited their stake in a long term deposit).
But yeah, in the end it indeed is a factor which is one of trade offs I mentioned, but there are ways to combat it.
Not everyone would want to do that, so there's usually a mechanism to indicate you want to be eligible to do so, depositing your coins or similar.
That's for block rewards - nothing prevents a blockchain currency to be designed to generate inflation and add interest on everyone's investment - some do exactly that.
