First, are you serious? You think the government bailouts negatively affected your 401k? The market was already doing that, due primarily to a lack of regulation. Such regulation can only come from the government, but government = evil according to you, so I guess there should have been LESS regulation or enforcement, but then your 401k would have lost even more than it did and you'd probably never get any of it back since most of the companies would have gone bankrupt and ceased to exist. And they'd probably foreclose on your home (when you lost your job and savings, having been laid off by one of those bankrupt companies and with your investments worth 0), and without social security and medicare and food stamps and all that, where would you be then?
The other problem is that if you are in the bottom 95% of the population, income-wise, you're probably not going to gain much through increased dividends, etc., certainly not like you would from a modest pay raise. (The top 1% does because most of their income comes from investments, not labor, and they have such high holdings that even a few percent increase can mean hundreds of thousands, if not millions, of extra income each year.) You even stand to gain a lot more through better government services or lower personal income taxes (less income taxation of the poor is needed if more of the money can come from corporate, investment, or other high-end taxes).
Note also in case you weren't paying attention for the past 50 years: Republicans do not cut government budgets. (I don't know that you're a Republican, just wanted to point this out.) They just spend the money on bombs and spying on people and putting people in jail, instead of spending it on helping people or investing in the future. But since they cut high-end taxes, they do increase deficits, and hence interest payments on the debt. Which means even less services or investment for your tax dollar.
This is the Republican paradox: slash taxes on the rich so that it takes higher taxes on the poor to pay for the very necessary government services that 99% of the population demands (and with good reason, as spreading the cost and risk and centralizing such things is almost always the best and cheapest way to do them, and many government investments result in much greater return to society down the line). Then they complain about how high poor people's taxes are (since, surprise, poor people pay about the same percent of total income to taxes - about 30% - as wealthy people do, regressive sales and payroll and other taxes canceling out slightly progressive income taxes). And they're right: taxes on poor people are too high, when many poor people can barely even pay rent on a crappy apartment or buy food for their family, let alone give 30% of it to the government. People also then complain about how crappy government services are, now that they've been cut due to insufficient funds and spending the money on useless crap and interest payments instead, so that Republicans can then say government = bad, and try to ram through MORE tax cuts for the rich, cut services even more (while still not cutting the overall budget, or taxes for poor people, one bit), complain more, etc.
This results in a continuous increase in concentration of wealth in the richest segment of the population. Which was the whole point.
So why do poor people vote for Republicans when it's not in their interest to do so? Republicans realized that a large subset of the population is stupid, ignorant, uneducated, racist, sexist, nervous, fearful, angry, and generally emotional rather than rational. Many of them happen to also be highly religious or hold to certain hot-button views. So all the Republicans need to do is pander to these people's base emotional "needs" and religious proclivities and hot-button issues to get their vote. Then they (the ones in power, who ACTUALLY represent the top 1% richest Americans) can run away with the money (including from the people that voted for them). And for the most part, the people that voted for them remain ignorant (I wonder why, if they watch Fox news all the time), and vote for the crooks again in the next election.
