Micro Limit versus small or regular limit

While this addresses Micro limit Mi_T_Sharp are having a debate about whether micro limit games are winnable. I believe they are not, Mi_T_Sharp says they are.

Both of us know the adage that if you can't win a lower limit, then you can't win a higher limit. I believe Micro limits are unwinnable, Mi_T_Sharp disagrees.

Here are my thoughts. Say you are in a nine person table and you have A-A, and everyone before you goes all-in. Should you call? I say no. Although you have the better odds than any particular player, at this point your odds of beating the entire table are less than 50%. So even though you have the best, against the whole table you are destined to lose b/c the other players combined have so many outs.

In other words, my position is that when everyone sees the flop, there is no way to win long term.

We are talking Micro here, $0.25/0.50 and below...we just want your thoughts.
