A nuclear power plant costs between $6B - $9B to build, before it generates any electricity, that is just the construction cost these days for a 1100MW plant
Regulatory costs for a nuclear power plant will range between $7M - $15M annually.
Do the math: it is definitely not the regulations. Any time someone complains about regulations, you know there is a Republican agenda. We need regulations, because they are the only thing preventing Big Business from enslaving you and me and worse. Regulations are good. Unless you make more than $400K/yr, stop doing the 1%er's jobs for them making sure most of the wealth is controlled by just a few by... removing regulations which really only bothers them because it means they make slightly less of the fortune they'd make without it.
The money is what is important. Your money should be important to you, so please make sure you only support agendas that work for your personal economic interests rather than the interests of the richest of the rich. If everyone always voted in their personal economic interests, we'd see a boom economy. The problem is, 99% of the Republican Party is literally voting adversely to their economic interests. They are voting to keep themselves economically stagnant and also to make sure the rich stay rich, for that day that will never come when they are rich, or maybe it is the absolute distractions that do not affect economy, like abortion or 2nd A. issues. If everyone only voted in their personal economic interests, and ignored all other concerns, there could not be a Republican Party. Well, there would be, but it would only have about 20 members, all listed among the top 25 richest Amercans. Most people aren't rich, and could benefit from better opportunity, which will never come so long as a minority party somehow has and has had control of the Senate for 18 of the last 20 years. If you care about your money, you should be on board with making DC and Puerto Rico legitimate US States, tax them and let them vote, and let's progress as a nation, rather than stagnating.
