Why does voting start so early

I just do not understand why voting starts so early for presidential elections. I am currently

 living in South Carolina and the voting started like 2 or 3 weeks before the election and it was

 everyday from morning to evening. If they are going to be starting voting so early then why

 not just hire enough people to go door to door. I believe this would be more secure can

 guarantee that there will be no illegal people voting, this would also make it so that every last

 person who would like to vote gets the chance to vote. The next best part is that they will have

 all the votes counted much faster, there will of course be them people that wait until election

 day to vote but I can bet that it will not be as big of lines as normal. I know I would like it and

 I know it can get does the proof of that is the census. I believe that it would be even better if 

they were to make an online portal that is secured with blockchain technology to do voting at

home. They could require biometrics like facial recognition so that they could verify your 

face with the picture on your ID that proves your citizenship.   

Corporations need fixed

 Every company I have worked for says they are safety first. That is a bunch of bull. The only company that I can think of that was safety first would have been FedEx Express. Now when you work in a factory the only thing that they care about is the product being made. If and surprise inspection were to be made on factories I can guarantee there would be a whole bunch of violations, always tripping hazards, half-fixed equipment that employees are forced to work with, and even supervisors who will try to put you down if you get hurt. I know this because I got hurt and was asked if I wanted a tampon in front of other people, the supervisor even had a woman employee come into the office so that he could ask her if she had a tampon she could give me. I have no idea what is happening to the companies in this country but it is quite clear that profit means a whole lot more to any company than the safety of their employees. 

Corporate Greed

 We all know that any business is greedy. The guys in the suits think they know everything. The people who do the work and know more than the executives who get all the credit and money are always the first to get wiped away like it doesn't matter. This world in the next few generations is going to change a lot. There will be very few if any jobs for anyone. The new employees will be robots with AI, the people in the suits who think they know everything are pushing for this. When this happens, people who think they will be saving money for the company will finally see that without the working people, their wealth will disappear. Why you ask well the working person is needed because they are the ones who spend the money and make people richer. With no jobs because of robots, the workers will not have money so the economy will collapse taking all of the rich people down with it. Before we all know it the monetary system will be obsolete because of technology.
