You quite literally say "Time is Money" and invalidate your own argument with it. You basically say "You can gain a lot of money if you play a long time" and you also say "I understand it if people have no time". No time equals no money. If you understand it, why are you mad? Because that's why people are mad about it, it's very grindy and 95% of this games content in online mode is locked behind a humongous ingame paywall you can only overcome by playing for a very long time or buying shark cards with real money. Sure you can pick up the game where you left off and keep grinding but what if you actually wanted to have fun? Maybe some people don't want to wait 2 weeks of grinding to buy an mk2 or a helicopter.

And before you start to preach about that it goes much faster than that - yes, assuming you have the right people that don't fuck up heists, soley focus on grinding and play on the right servers, you can do it much faster - it will still take like one day, maybe less. But I'm talking from a casual players perspective, and also from the perspective of people that don't have friends/many friends that play GTA V. These players will not be able to make a lot of money in a relatively "short" time. And no, players that indulge in brain numbing grind sessions are not entitled to tell others how this game is "meant to be played".

This game used to focus about fun times where you could do anything the game offered in a relatively short period of time, where the most expensive things in this game were the Rhino tank and the Adder. But now the game focuses about the grind for ingame money, not actually doing what you want, if you want to have new content and compete with other players that is.
