This is what happens in some Republican controlled states when they limit the times and places and how people can vote. Trump said a few years ago that if minorities vote, Republicans will never win another election. So Republican controlled states started getting rid of polling stations and changing voting times to standard working hours, etc, knowing that people wouldn't be able to take time off from work to stand in the now longer lines (due to fewer polling stations) or would want to stand in longer lines.

Plus, election day is not a national holiday like it is in most other countries, so people don't get the day off to vote. Though some companies give 3 or 4 hours paid time off strictly for voting.
