But as happened in Marietta Ga recently, the government officials had already committed the county to 600 million for a new stadium. They got voted out, but the county is still stuck with the bill.

Nitpick: it was Cobb County. But yeah the damage was done regardless, and now the county is left trying to find ways to pay for what it committed to, by increasing taxes and/or poaching money from other services like public schools.

Yeah not saying it's perfect. But it's better than those people staying in power, and with the AK-47s.

No, you can't; deals involving this much money are beyond local politics. For example, Washington's governor just vetoed a measure that would extend state tax cuts to manufacturing companies that aren't called Boeing, and he's not going anywhere.

And even if people do complain, all your mayor/city council has to do to win re-election is claim that all the jobs would disappear if they didn't offer the incentives. You can't do anything about this, it's just blatant corruption endemic to the system.

I'm not arguing for a ban, but here would be the argument: It's clearly unethical, undesirable behavior, but even if a particular municipality didn't like the game, it's tough not to play (much like taking corporate donations for political campaigns). So instead of trying to live the libertarian good life of "Our city is better than that" and losing because someone else has fewer scruples, it is proposed that the practice be banned.

I guess I would disagree with the "it's clearly unethical, undesirable behavior" part. I just don't think it's clearly good nor clearly bad.

I think it isn't in theory (jobs! tax revenue from families!) but how often do these things play out?

No idea ¯\_(ツ)_/¯
