Yes, many people are being attracted to forex, but sooner or later most of them will get away because of the extreme difficulty of forex. I read a poll at MoneyTec showing that most of traders have burned their accounts and quited. Forex is difficult, might be because the forex market moves without any reason at all, while the stocks most of the time moves with reasons.
Yes, all brokers do care about the winning and losing of their customers. All of them want their clients to stay longer, so that they can collect for spreads. Oanda, for example, offers a max leverage of 50:1 to help newbies stay longer. All of them oftenly provide all kinds of resources including economic calendar, news, market analysis, daily signals, trades stats, etc.
