What limits do you play at? If it's micro-limits, an aggressive style of play won't work; you'll be taken away or even outplayed with useless cards.
I play mostly micro limits.
I understand what you mean because they don't fold.
In this case they it is even more important to raise and even 3-bet a standard amount with good cards.
The math demands more money in the pot when you have good cards. That is....if you want to win more chips.
If 5 players call you down every street then it is likely one of them will get there by the river to beat you.
Other times you will win a big pot because your opponents are contributing and paying to draw more cards.
