so people here are trying to tell me that 50 amp service is only 20 amps more than 30 amp service, and not 70 amps more? that certainly isn't what posts have said over the years. and I don't see why the fact that the neutral balances out to zero really affects this situation, other than size needed of the neutral wire.

It is 50 amps at 240 volts or 12,000 watts vs 30 amps at 120 volts or 3,600 watts. Lots of difference. Just never referred to as 100 amps.
The neutral only needs to carry the imbalance of the two hot legs when it is wired properly. The neutral is always sized to match the hot legs. If the hot legs are of the same phase, there would not be opposite phases to balance and the neutral would be required to carry everything both hot legs are carrying. This creates a very dangerous situation when trying to say this is strictly a 120v connection when it should be in fact a 240 connection.
you have stated exactly what I have read here in the past. don't know why some folks here are trying to confuse things.
