I think Singles (younger & older) should be able to pick who they want to marry! I mean you are old enought to GET married, why not be able to pick that person?
I’m not sure why we throw ourselves at the mercy of Shadchanim, who gave these people Ruach Hakodesh? Does it say anywhere that you have to go through a certain amount of boosha by begging and pleading before you can get a date kal vachomer married?
Maybe this system worked in Europe where people where told at 13 who they were going to marry at 16. Now that we have options, opinions, veto power (not to mention the shrinking world) this system simply cant and doesnt work!
